See the sections below for detailed instructions.NOTE Before configuring any WAN properties for an IPv6 network, you must configure the routing mode. Choose NNetworking > IIPv6 > RRouting Mode and select IPv4 / IPv6 mode. Click SSave.The Cisco RV 120W can be configured to be a DHCPv6 client of the ISP for this WAN or a static IPv6 address provided by the ISP can be assigned. Configuring a Static IP AddressIf your ISP assigns you a fixed address to access the Internet, choose this option. The information needed for configuring a static IP address can be obtained from your ISP.STEP 1 In the IInternet Address field, choose SStatic IPv6.STEP 2 Enter the IPv6 IP address assigned to your router.STEP 3 Enter the IPv6 prefix length defined by the ISP. The IPv6 network (subnet) is identified by the initial bits of the address which are called the prefix (for example, in the IP address 2001:0DB8:AC10:FE01::, 2001 is the prefix). All hosts in the network have identical initial bits for their IPv6 address; the number of common initial bits in the network’s addresses is set in this field.STEP 4 Enter the default IPv6 gateway address, or the IP address of the server at the ISP that this router will connect to for accessing the internet.
Configuring NetworkingConfiguring the Wide Area Network (WAN)Cisco RV 120W Administration Guide 352 STEP 5 Enter the primary and secondary DNS server IP addresses on the ISP's IPv6 network. DNS servers map Internet domain names (for example, www.cisco.com) to IP addresses.STEP 6 Choose the method by which the router obtains an IP address:STEP 7 Click SSave.Configuring DHCPv6When the ISP allows you to obtain the WAN IP settings via DHCP, you need to provide details for the DHCPv6 client configuration. STEP 1 In the Internet Address field, choose DDHCPv6. STEP 2 Choose if the DHCPv6 client on the gateway is stateless or stateful. If a stateful client is selected, the gateway connects to the ISP's DHCPv6 server for a leased address. For stateless DHCP, it is not necessary to have a DHCPv6 server available at the ISP. Instead, a ICMPv6 discover messages will originate from the Cisco RV 120W and is used for auto-configuration. STEP 3 Click SSave.Creating PPPoE ProfilesYou can create profiles for multiple PPPoE accounts, which can be useful if you connect to the Internet using different service provider accounts. STEP 1 Choose NNetworking > WWAN > PPPPoE Profiles. Click AAdd to create a new profile.STEP 2 Enter the profile name. This is a label that you choose to identify the profile (for example, “ISPOne”).STEP 3 Enter the username and password. These are assigned to you by the ISP to access your account.STEP 4 Choose the authentication type:•Auto-negotiate—The server sends a configuration request specifying the security algorithm set on it. The router then sends back authentication credentials with the security type sent earlier by the server.

If the connection is idle—that is, no traffic is occurring—the connection is closed. You might want to choose this if your ISP charges based on the amount of time that you are connected. If you choose this connection type, enter the number of minutes after which the connection shuts off in the IIdle Time field.STEP 6 Click SSave. Your new profile is added to the list.Configuring the Local Area Network (LAN)For most applications, the default DHCP and TCP/IP settings are satisfactory. If you want another PC on your network to be the DHCP server, or if you are manually configuring the network settings of all of your PCs, disable DHCP. Instead of using a DNS server, you can use a Windows Internet Naming Service (WINS) server. A WINS server is the equivalent of a DNS server but uses the NetBIOS protocol to resolve hostnames. The router includes the WINS server IP address in the DHCP configuration when acknowledging a DHCP request from a DHCP client.You can also enable a DNS proxy. When enabled, the router then acts as a proxy for all DNS requests and communicates with the ISP's DNS servers. When disabled, all DHCP clients receive the DNS IP addresses of the ISP.
Configuring NetworkingConfiguring the Local Area Network (LAN)Cisco RV 120W Administration Guide 372 If machines on your LAN use different IP address ranges (for example, 172.16.2.0 or 10.0.0.0), you can add aliases to the LAN port to give PCs on those networks access to the Internet. This allows the firewall to act as a gateway to additional logical subnets on your LAN. You can assign the firewall an IP address on each additional logical subnet.NOTE If you have IPv6 configured, see “Configuring IPv6 LAN Properties” on page 43.Changing the Default Cisco RV 120W IP AddressSTEP 1 Choose NNetworking > LLAN > LLAN Configuration.STEP 2 In the IP address field, enter the new IP address for your Cisco RV 120W. The default IP address is 192.168.1.1. You might want to change the default IP address if that address is assigned to another piece of equipment in your network.STEP 3 Enter the Subnet Mask for the new IP address.STEP 4 Click SSave. After changing the IP address, you are no longer connected to the Cisco RV 120W. You must do one of the following:•Release and renew the IP address on the PC that you are using to access the Cisco RV 120W (if DHCP is configured on the router).•Manually assign an IP address to your PC that is in the same subnet as the Cisco RV 120W. For example, if you change the Cisco RV 120W IP address to 10.0.0.1, you would assign an IP address in the 10.0.0.0 subnet to your PC.STEP 5 Open a new browser window and enter the new IP address of the Cisco RV 120W to re-connect.Configuring DHCPBy default, the Cisco RV 120W functions as a DHCP server to the hosts on the Wireless LAN (WLAN) or LAN network and assigns IP and DNS server addresses.With DHCP enabled, the router's IP address serves as the gateway address to your LAN. The PCs in the LAN are assigned IP addresses from a pool of addresses. Each address is tested before it is assigned to avoid duplicate addresses on the LAN.
Configuring NetworkingConfiguring the Local Area Network (LAN)Cisco RV 120W Administration Guide 382 STEP 1 Choose NNetworking > LLAN > LLAN Configuration.STEP 2 In the DHCP Section, in the DHCP Mode field, choose one of the following:•DHCP Server—Choose this to allow the Cisco RV 120W to act as the DHCP server in the network. Enter the following information:-Domain Name—Enter the domain name for your network (optional).-Starting and Ending IP Address—Enter the first and last of the contiguous addresses in the IP address pool. Any new DHCP client joining the LAN is assigned an IP address in this range. You can save part of the range for PCs with fixed addresses. These addresses should be in the same IP address subnet as the router's LAN IP address.-Primary and Secondary DNS Server—DNS servers map Internet domain names (for example, www.cisco.com) to IP addresses. Enter the server IP addresses in these fields if you want to use different DNS servers than are specified in your WAN settings.-Lease time—Enter the duration (in hours) for which IP addresses are leased to clients.•DHCP Relay—If you chose DHCP Relay as the DHCP mode, enter the address of the relay gateway in the Relay Gateway field. The relay gateway transmits DHCP messages between multiple subnets.•None—Use this to disable DHCP on the Cisco RV 120W. If you want another PC on your network to be the DHCP server, or if you are manually configuring the network settings of all of your PCs, disable DHCP.STEP 3 Click SSave.Configuring the LAN DNS ProxySTEP 1 Choose NNetworking > LLAN > LLAN Configuration.STEP 2 In the LAN Proxy section, to enable the Cisco RV 120W to act as a proxy for all DNS requests and communicate with the ISP's DNS servers, check EEnable DNS Proxy. When this feature is enabled, the router acts as a proxy for all DNS requests and communicates with the ISP's DNS servers (as configured in the WAN settings page). All DHCP clients receive the Primary/Secondary DNS IP and the IP of the router where DHCP is running. All DHCP clients receive the DNS IP addresses of
Configuring NetworkingConfiguring the Local Area Network (LAN)Cisco RV 120W Administration Guide 392 the ISP, excluding the DNS Proxy IP address when it is disabled. The feature is useful for an “auto rollover” configuration. For example, if the DNS servers for each connection are different, then a link failure can render the DNS servers inaccessible. However, when the DNS proxy is enabled, then clients can make requests to the router and the router, in turn, sends those requests to the DNS servers of the active connection. STEP 3 Click SSave.Configuring Virtual LANs (VLANs)A VLAN is a group of endpoints in a network that are associated by function or other shared characteristics. Unlike LANs, which are usually geographically based, VLANs can group endpoints without regard to the physical location of the equipment or users.

STEP 5 Choose the DHCP mode. If stateless is selected, an external IPv6 DHCP server is not required as the IPv6 LAN hosts are auto-configured by the Cisco RV 120W. In this case, the router advertisement daemon (RADVD) must be configured on this device and ICMPv6 router discovery messages are used by the host for auto-configuration. There are no managed addresses to serve the LAN nodes. If stateful is selected, the IPv6 LAN host will rely on an external DHCPv6 server to provide required configuration settings. STEP 6 (Optional) Enter the domain name of the DHCPv6 server.STEP 7 Enter the server preference. This field is used to indicate the preference level of this DHCP server. DHCP advertise messages with the highest server preference value to a LAN host are preferred over other DHCP server advertise messages. The default is 255.STEP 8 Choose the DNS proxy behavior:•Use DNS Proxy—Check this box to enable DNS proxy on this LAN, or uncheck this box to disable this proxy. When this feature is enabled, the router acts as a proxy for all DNS requests and communicate with the ISP’s DNS servers (as configured in the WAN settings page).•Use DNS from ISP—This option allows the ISP to define the DNS servers (primary/secondary) for the LAN DHCP client.•Use below—If selected, the primary/secondary DNS servers configured are used. If you chose this option, enter the IP address of the primary and secondary DNS servers. STEP 9 Enter the lease/rebind time. Enter the duration (in seconds) for which IP addresses will be leased to endpoints on the LAN.STEP 10 Click SSave.Configuring IPv6 Address PoolsThis feature allows you to define the IPv6 delegation prefix for a range of IP addresses to be served by the Cisco RV 120W’s DHCPv6 server. Using a delegation prefix, you can automate the process of informing other networking equipment on the LAN of DHCP information specific for the assigned prefix.
Configuring NetworkingConfiguring the Local Area Network (LAN)Cisco RV 120W Administration Guide 452 STEP 1 Choose NNetworking > LLAN > IIPv6 LAN Configuration.STEP 2 In the List of Address Pools field, click AAdd.STEP 3 Enter the starting IP address and ending IP address of the pool.STEP 4 Enter the prefix length. The number of common initial bits in the network’s addresses is set by the prefix length field.STEP 5 Click SSave.Configuring LAN GroupsYou can create LAN groups, which are groups of endpoints that are identified by their IP address. After creating a group, you can then configure actions, such as blocked keywords in a firewall rule, that apply to the group. (See Adding Blocked Keywords, page 87.)To create a LAN Group: STEP 1 Choose NNetworking > LLAN > LLAN Groups.STEP 2 Click AAdd.STEP 3 Enter the group name; spaces and quotes are not supported. Click SSave. STEP 4 In the LAN Groups page, click the box next to the group you just created and click Host List.STEP 5 To add endpoints to the group, click AAdd.STEP 6 Enter the IP address of the endpoint and click SSave. Repeat steps 4 through 6 for each endpoint you want to add to the group.Adding a Static IP Address for a Device on the LANYou can configure an IP Address and MAC Address for a known computer or device on the LAN network from the LAN Interface menu.
Configuring NetworkingConfiguring the Local Area Network (LAN)Cisco RV 120W Administration Guide 462 STEP 1 Choose NNetworking > LLAN > SStatic DHCP (LAN).STEP 2 Click AAdd.STEP 3 Enter the IP address of the device.STEP 4 Enter the MAC address of the device. The format for the MAC Address is XX:XX:XX:XX:XX:XX where X is a number from 0 to 9 (inclusive) or an alphabetical letter between A and F (inclusive).NOTE The IP Address assigned should be outside the pool of the DHCP addresses configured. The DHCP pool is treated as generic pool and all reserved IP's should be outside this pool. The DHCP server will then serve the reserved IP address when the device using the corresponding MAC address requests an IP address.Viewing DHCP Leased ClientsYou can view a list of endpoints on the network (identified by MAC address) and see the IP address assigned to them by the DHCP server. The VLAN of the endpoint is also displayed.STEP 1 Choose NNetworking > LLAN > DDHCP Leased Clients (LAN).STEP 2 The list of endpoints is displayed; you cannot edit this list.Configuring a DMZ HostThe Cisco RV 120W supports DMZ options. A DMZ is a sub-network that is open to the public but behind the firewall. DMZ allows you to redirect packets going to your WAN port IP address to a particular IP address in your LAN. It is recommended that hosts that must be exposed to the WAN (such as web or e-mail servers) be placed in the DMZ network. Firewall rules can be allowed to permit access to specific services and ports to the DMZ from both the LAN or WAN. In the event of an attack on any of the DMZ nodes, the LAN is not necessarily vulnerable as well.
Configuring NetworkingConfiguring the Local Area Network (LAN)Cisco RV 120W Administration Guide 472 You must configure a fixed (static) IP address for the endpoint that will be designated as the DMZ host. The DMZ host should be given an IP address in the same subnet as the router's LAN IP address but it cannot be identical to the IP address given to the LAN interface of this gateway. STEP 1 Choose NNetworking > LLAN > DDMZ Host.STEP 2 Check the EEnable box to enable DMZ on the network.STEP 3 Enter the IP address for the endpoint that will receive the redirected packets. This is the DMZ host.STEP 4 Click SSave. You must then configure firewall rules for the zone. See Configuring Firewall Rules, page 79.Configuring Internet Group Management Protocol (IGMP)Internet Group Management Protocol (IGMP) is an exchange protocol for routers. Hosts that want to receive multicast messages need to inform their neighboring routers of their status. In some networks, each node in a network becomes a member of a multicast group and receives multicast packets. In these situations, hosts exchange information with their local routers using IGMP. Routers use IGMP periodically to check if the known group members are active. IGMP provides a method called dynamic membership by which a host can join or leave a multicast group at any time. To configure IGMP:STEP 1 Choose NNetworking > LLAN > IIGMP Configuration.STEP 2 Check the EEnable box to allow IGMP communication between the router and other nodes in the network.STEP 3 Click SSave.
Configuring NetworkingConfiguring RoutingCisco RV 120W Administration Guide 482 Configuring RoutingChoosing the Routing ModeThe Cisco RV 120W provides two different routing modes. Network Address Translation (NAT) is a technique that allows several endpoints on a LAN to share an Internet connection. The computers on the LAN use a “private” IP address range while the WAN port on the router is configured with a single “public” IP address. The Cisco RV 120W translates the internal private addresses into a public address, hiding internal IP addresses from computers on the Internet. If your ISP has assigned you a single IP address, you want to use NAT so that the computers that connect through the Cisco RV 120W are assigned IP addresses from a private subnet (for example, 192.168.10.0). The other routing mode, “classical routing,” is used if your ISP has assigned you multiple IP addresses so that you have an IP address for each endpoint on your network. You must configure either static or dynamic routes if you use this type of routing. See Configuring Static Routing, page 49, or Configuring Dynamic Routing, page 50.To choose your routing mode:STEP 1 Select NNetworking > RRouting > RRouting Mode.STEP 2 Click the box next to the type of routing to configure (“NAT” or “Routing”) and click Save.NOTE If you have already configured DMZ or firewall settings on your router in NAT mode, selecting “router” changes those settings back to the default.Viewing Routing InformationTo view routing information your network, choose NNetworking > RRouting > RRouting Table. Information about your network routing is displayed, including the following:•Destination—Destination host/network IP address for which this route is added.•Gateway—The gateway used for this route.
Configuring NetworkingConfiguring RoutingCisco RV 120W Administration Guide 492 •Genmask—The netmask for the destination network.•Flags—For debugging purpose only; possible flags include:-U—Route is up.-H—Target is a host.-G—Use gateway.-R—Reinstate route for dynamic routing.-D—Dynamically installed by daemon or redirect.-M—Modified from routing daemon or redirect.-A—Installed by addrconf.-C—Cache entry.-!—Reject route.•Metric—The distance to the target (usually counted in hops).•Ref—Number of references to this route.•Use—Count of lookups for the route. Depending on the use of -F and -C, this is either route cache misses (-F) or hits (-C).•Iface—Interface to which packets for this route will be sent.Configuring Static RoutingYou can configure static routes to direct packets to the destination network. A static route is a pre-determined pathway that a packet must travel to reach a specific host or network. Some ISPs require static routes to build your routing table instead of using dynamic routing protocols. Static routes do not require CPU resources to exchange routing information with a peer router. You can also use static routes to reach peer routers that do not support dynamic routing protocols. Static routes can be used together with dynamic routes. Be careful not to introduce routing loops in your network.To create a static route:STEP 1 Select NNetworking > RRouting > SStatic Routing.STEP 2 In the list of static routes, click AAdd.
Configuring NetworkingConfiguring RoutingCisco RV 120W Administration Guide 502 STEP 3 Enter the route name.STEP 4 If a route is to be immediately active, check the AActive box. When a route is added in an inactive state, it will be listed in the routing table, but will not be used by the router. The route can be enabled later. This feature is useful if the network that the route connects to is not available when you added the route. When the network becomes available, the route can be enabled. STEP 5 Check the PPrivate box to mark this route as private, which means that it will not be shared in a Routing Information Protocol (RIP) broadcast or multicast. Uncheck this box if the route can be shared with other routers when RIP is enabled.STEP 6 In the destination IP address field, enter the IP address of the destination host or network to which the route leads. For a standard Class C IP domain, the network address is the first three fields of the Destination LAN IP; the last field should be zero.STEP 7 In the IP subnet mask field, enter the IPv4 Subnet Mask for the destination host or network. For Class C IP domains, the Subnet Mask is 255.255.255.0.STEP 8 Choose the physical network interface through which this route is accessible (WWAN or LLAN).STEP 9 In the gateway IP address field, enter the IP Address of the gateway through which the destination host or network can be reached. If this router is used to connect your network to the Internet, then your gateway IP is the router's IP address. If you have another router handling your network's Internet connection, enter the IP address of that router instead.STEP 10 In the metric field, enter a value between 2 and 15 to define the priority of the route. If multiple routes to the same destination exist, the route with the lowest metric is chosen.STEP 11 Click SSave.Configuring Dynamic RoutingRIP (Routing Information Protocol, RFC 2453) is an Interior Gateway Protocol (IGP) that is commonly used in internal networks. It allows the router to exchange its routing information automatically with other routers, and allows it to dynamically adjust its routing tables and adapt to changes in the network.
Configuring NetworkingConfiguring RoutingCisco RV 120W Administration Guide 512 NOTE RIP is disabled by default on the Cisco RV 120W.To configure dynamic routing:STEP 1 Choose NNetworking > RRouting > DDynamic Routing.STEP 2 To configure how the router sends and receives RIP packets, choose the RIP direction: •Both—The router both broadcasts its routing table and also processes RIP information received from other routers. •Out Only—The router broadcasts its routing table periodically but does not accept RIP information from other routers. •In Only—The router accepts RIP information from other router, but does not broadcast its routing table.•None—The router neither broadcasts its route table nor does it accept any RIP packets from other routers. This option disables RIP.STEP 3 Choose the RIP version:•Disabled.•RIP-1—This is a class-based routing version that does not include subnet information. RIP-1 is the most commonly supported version. •RIP-2B—This version broadcasts data in the entire subnet.•RIP-2M—This version sends data to multicast addresses. STEP 4 RIP v2 authentication forces authentication of RIP packets before routes are exchanged with other routers. It acts as a security feature because routes are exchanged only with trusted routers in the network. RIP authentication is disabled by default. You can enter two key parameters so that routes can be exchanged with multiple routers present in the network. The second key also acts as a failsafe when authorization with first key fails.To enable authentication for RIP-2B or RIP-2M, check the EEnable box. (You must also choose the direction as explained in SStep 1.)If you enabled RIP v2 authentication, enter the following first and second key parameters:
Configuring NetworkingConfiguring Port ManagementCisco RV 120W Administration Guide 522 •MD5 Key ID—Input the unique MD-5 key ID used to create the Authentication Data for this RIP v2 message.•MD5 Auth Key—Input the auth key for this MD5 key, the auth key that is encrypted and sent along with the RIP-V2 message.•Not Valid Before—Enter the start date when the auth key is valid for authentication.•Not Valid After—Enter the end date when the auth key is valid for authentication.STEP 5 Click SSave. Configuring Port ManagementThe Cisco RV 120W has four LAN ports. You can enable or disable ports, configure if the port is half- or full-duplex, and set the port speed.To configure LAN ports:STEP 1 Choose NNetworking > PPort Management.STEP 2 To enable a port, check the Enable box. To disable the port, uncheck the EEnable box. By default, all ports are enabled. STEP 3 Check the AAuto box to let the router and network determine the optimal port settings. By default, automatic mode is enabled. This setting is available only when the EEnable box is checked.STEP 4 (Optional) Choose either half- or full-duplex based on the port support. The default is full-duplex for all ports. This setting is available only when the AAuto check box is unchecked.STEP 5 (Optional) Select one of the following port speeds: 110 Mbps or 1100 Mbps. The default setting is 100 Mbps for all ports. This setting is available only when the Auto check box is unchecked. You can change the port speed if a network is designed to run at a particular speed, such as 10 Mbps mode. In this case, the endpoint also uses 10 Mbps mode either by auto-negotiation or manual setting. STEP 6 Click SSave.
Configuring NetworkingConfiguring Dynamic DNS (DDNS)Cisco RV 120W Administration Guide 532 Configuring Dynamic DNS (DDNS)DDNS is an Internet service that allows routers with varying public IP addresses to be located using Internet domain names. To use DDNS, you must set up an account with a DDNS provider such as DynDNS.com or TZO.com. The router will notify dynamic DNS servers of changes in the WAN IP address, so that any public services on your network can be accessed by using the domain name.To configure DDNS:STEP 1 Choose NNetworking > DDynamic DNS.STEP 2 Select the Dynamic DNS Service you are using. Selecting NNone disables this service.STEP 3 If you selected DynDNS.com:a. Specify the complete Host Name and Domain Name for the DDNS service. b. Enter the DynDNS account username. c. Enter the password for the DynDNS account.d. Check the UUse Wildcards box to enable the wildcards feature, which allows all subdomains of your DynDNS Host Name to share the same public IP as the Host Name. This option can be enabled here if not done on the DynDNS Web site. e. Check the UUpdate Every 30 Days box to configure the router to update the host information on DynDNS and keep the subscription active after the 30-day trial.If you selected TZO.com:a. Specify the complete Host Name and Domain Name for the DDNS service. b. Enter the user e-mail address for the TZO account. c. Enter the user key for the TZO account.d. Check the UUpdate Every 30 Days box to configure the router to update the host information on TZO.com and keep the subscription active after the 30-day trial.

When a route is added in an inactive state, it will be listed in the routing table, but will not be used by the router. The route can be enabled later. This feature is useful if the network that the route connects to is not available when you added the route. When the network becomes available, the route can be enabled. STEP 5 In the IPv6 destination field, enter the IPv6 address of the destination host or network for this route.STEP 6 In the IPv6 prefix length field, enter the number of prefix bits in the IPv6 address that define the destination subnet. STEP 7 Choose the physical network interface through which this route is accessible (WWAN, LLAN, or ssit0 tunnel). (The Simple Internet Transition [SIT] is a set of protocol mechanisms implemented in hosts and routers, along with some operational guidelines for addressing and deployment, designed to make the transition from the Internet to IPv6 work with as little disruption as possible. The SIT0 tunnel is a point-to-point tunnel.)STEP 8 Enter the IP Address of the gateway through which the destination host or network can be reached. STEP 9 In the metric field, specify the priority of the route by choosing a value between 2 and 15. If multiple routes to the same destination exist, the route with the lowest metric is used. STEP 10 Click SSave.Configuring RIP next generation (RIPng)RIPng (RFC 2080) is a routing protocol based on the distance vector (D-V) algorithm. RIPng uses UDP packets to exchange routing information through port 521. RIPng uses a hop count to measure the distance to a destination. The hop count is referred to as metric, or cost. The hop count from a router to a directly-connected network is 0. The hop count between two directly-connected routers is 1. When the hop count is greater than or equal to 16, the destination network or
Configuring NetworkingConfiguring IPv6Cisco RV 120W Administration Guide 562 host is unreachable. By default, the routing update is sent every 30 seconds. If the router receives no routing updates from a neighbor after 180 seconds, the routes learned from the neighbor are considered as unreachable. After another 240 seconds, if no routing update is received, the router will remove these routes from the routing table.On the Cisco RV 120W, RIPng is disabled by default.To configure RIPng:STEP 1 Select NNetworking > IIPv6 > RRouting (RIPng).STEP 2 Check the EEnable RIPng box.STEP 3 Click SSave.Configuring IPv6 to IPv4 TunnelingThe Cisco RV 120W provides several IPv6 tunneling methods.Configuring 6to4 Tunneling6to4 tunneling allows IPv6 packets to be transmitted over an IPv4 network. 6to4 tunneling is typically used when a site or end user wants to connect to the IPv6 Internet using the existing IPv4 network. To configure 6to4 Tunneling:STEP 1 Select NNetworking > IIPv6 > 66to4 Tunneling.STEP 2 Check the EEnable Automatic Tunneling box.STEP 3 Click SSave.Configuring Intra-Site Automatic Tunnel Addressing Protocol TunnelsIntra-site automatic tunnel addressing protocol is a method to transmit IPv6 packets between dual-stack nodes over an IPv4 network. The Cisco RV 120W is one endpoint (a node) for the tunnel. You must also set a local endpoint, as well as the ISATAP Subnet Prefix that defines the logical ISATAP subnet to configure a tunnel.
Configuring NetworkingConfiguring IPv6Cisco RV 120W Administration Guide 572 To add an ISATAP tunnel:STEP 1 Choose NNetworking > IIPv6 > IISATAP Tunnels.STEP 2 Click AAdd.STEP 3 Enter the ISATAP subnet prefix. This is the 64-bit subnet prefix that is assigned to the logical ISATAP subnet for this intranet. This can be obtained from your ISP or internet registry, or derived from RFC 4193. STEP 4 Choose the local endpoint address, or the endpoint address for the tunnel that starts with the Cisco RV 120W. The endpoint can be the LAN interface (if the LAN is configured as an IPv4 network), or a specific LAN IPv4 address. STEP 5 If you chose an endpoint other than the LAN interface in Step 4, enter the IPv4 address of the endpoint.STEP 6 Click SSave.Viewing IPv6 Tunnel InformationTo view IPv6 tunnel information, choose NNetworking > IIPv6 > IIPv6 Tunnels Status.The page displays information about the automatic tunnel set up through the dedicated WAN interface. The table shows the name of tunnel and the IPv6 address that is created on the device.Configuring Router Advertisement The Router Advertisement Daemon (RADVD) on the Cisco RV 120W listens for router solicitations in the IPv6 LAN and responds with router advertisements as required. This is stateless IPv6 auto configuration, and the Cisco RV 120W distributes IPv6 prefixes to all nodes on the network.To configure the RADVD:STEP 1 Choose NNetworking > IIPv6 > RRouter Advertisement.STEP 2 Under RADVD Status, choose EEnable.STEP 3 Under Advertise Mode, choose one of the following:•Unsolicited Multicast—Select this option to send router advertisements (RAs) to all interfaces belonging to the multicast group.
Configuring NetworkingConfiguring IPv6Cisco RV 120W Administration Guide 582 •Unicast only—Select this option to restrict advertisements to well-known IPv6 addresses only (router advertisements [RAs] are sent to the interface belonging to the known address only).STEP 4 If you chose Unsolicited Multicast in Step 3, enter the advertise interval. The advertise interval is a random value between the Minimum Router Advertisement Interval and Maximum Router Advertisement Interval. (MinRtrAdvInterval = 0.33 * MaxRtrAdvInterval.) The default is 30 seconds.STEP 5 Under RA Flags, check MManaged to use the administered/stateful protocol for address auto configuration. Check OOther to use the administered/stateful protocol of other, non-address information auto configuration.STEP 6 Under router preference, choose llow, mmedium, or hhigh. The router preference provides a preference metric for default routers. The low, medium and high values are signaled in unused bits in Router Advertisement messages. This extension is backward compatible, both for routers (setting the router preference value) and hosts (interpreting the router preference value). These values are ignored by hosts that do not implement router preference. This feature is useful if there are other RADVD-enabled devices on the LAN. The default is high. STEP 7 Enter the MTU size. The MTU is the size of the largest packet that can be sent over the network. The MTU is used in RAs to ensure all nodes on the network use the same MTU value when the LAN MTU is not well-known. The default is 1500 bytes.STEP 8 Enter the router lifetime value, or the time in seconds that the advertisement messages will exist on the route.

3Cisco RV 120W Administration Guide 60 Configuring the Wireless NetworkThis chapter describes how to configure your wireless network and includes the following sections:•A Note About Wireless Security, page 60•Understanding the Cisco RV 120W’s Wireless Networks, page 63•Configuring Access Points, page 66•Configuring the Wireless Radio Properties, page 70•Configuring the Wireless Radio Properties, page 70•Configuring Wi-Fi Protected Setup, page 72•Configuring a Wireless Distribution System (WDS), page 73A Note About Wireless SecurityWireless networks are convenient and easy to install, so homes with high-speed Internet access are adopting them at a rapid pace. Because wireless networking operates by sending information over radio waves, it can be more vulnerable to intruders than a traditional wired network. Like signals from your cellular or cordless phones, signals from your wireless network can also be intercepted. The following information will help you to improve your security:•Wireless Security Tips, page 60•General Network Security Guidelines, page 62Wireless Security TipsSince you cannot physically prevent someone from connecting to your wireless network, you need to take some additional steps to keep your network secure:
Configuring the Wireless NetworkA Note About Wireless SecurityCisco RV 120W Administration Guide 613 •Change the default wireless network name or SSIDWireless devices have a default wireless network name or Service Set Identifier (SSID) set by the factory. This is the name of your wireless network, and can be up to 32 characters in length. You should change the wireless network name to something unique to distinguish your wireless network from other wireless networks that may exist around you, but do not use personal information (such as your Social Security number) because this information may be available for anyone to see when browsing for wireless networks. •Change the default passwordFor wireless products such as access points, routers, and gateways, you will be asked for a password when you want to change their settings. These devices have a default password set by the factory. The default password is often aadmin. Hackers know these defaults and may try to use them to access your wireless device and change your network settings. To thwart any unauthorized changes, customize the device’s password so it will be hard to guess.•Enable MAC address filteringCisco routers and gateways give you the ability to enable Media Access Control (MAC) address filtering. The MAC address is a unique series of numbers and letters assigned to every networking device. With MAC address filtering enabled, wireless network access is provided solely for wireless devices with specific MAC addresses. For example, you can specify the MAC address of each computer in your network so that only those computers can access your wireless network.
Configuring the Wireless NetworkA Note About Wireless SecurityCisco RV 120W Administration Guide 623 •Enable encryptionEncryption protects data transmitted over a wireless network. Wi-Fi Protected Access (WPA/WPA2) and Wired Equivalency Privacy (WEP) offer different levels of security for wireless communication. Currently, devices that are Wi-Fi certified are required to support WPA2, but are not required to support WEP.A network encrypted with WPA/WPA2 is more secure than a network encrypted with WEP, because WPA/WPA2 uses dynamic key encryption. To protect the information as it passes over the airwaves, you should enable the highest level of encryption supported by your network equipment. WEP is an older encryption standard and may be the only option available on some older devices that do not support WPA.•Keep wireless routers, access points, or gateways away from exterior walls and windows.•Turn wireless routers, access points, or gateways off when they are not being used (at night, during vacations).•Use strong passphrases that are at least eight characters in length. Combine letters and numbers to avoid using standard words that can be found in the dictionary. General Network Security GuidelinesWireless network security is useless if the underlying network is not secure. Cisco recommends that you take the following precautions:•Password protect all computers on the network and individually password protect sensitive files.•Change passwords on a regular basis.•Install anti-virus software and personal firewall software.•Disable file sharing (peer-to-peer). Some applications may open file sharing without your consent and/or knowledge.
Configuring the Wireless NetworkUnderstanding the Cisco RV 120W’s Wireless NetworksCisco RV 120W Administration Guide 633 Understanding the Cisco RV 120W’s Wireless NetworksThe Cisco Small Business RV 120W Wireless-N VPN Firewall provides four Wireless Access Points (APs), or virtual wireless networks. These networks can be configured and enabled with individual settings. You can set up multiple networks to segment the network traffic, to allow different levels of access, such as guest access, or to allow access for different functions such as accounting, billing, and so on.You can further customize wireless access by creating profiles. A profile is a set of generic wireless settings that can be shared across multiple APs. Profiles allow you to easily duplicate SSIDs, security settings, encryption methods, and client authentication for multiple APs. Configuring Wireless ProfilesA profile is a set of generic wireless settings that can be shared across multiple APs. You can create multiple profiles on the Cisco RV 120W, but only one profile is assigned to each AP at a time.The Cisco RV 120W provides four default wireless profiles. EEven if you are not going to create custom profiles, at a minimum, you should edit the default profiles to enable wireless security. See A Note About Wireless Security, page 60.To configure wireless profiles:STEP 1 Choose WWireless > AAP Profiles.STEP 2 In the Profiles Table, either click AAdd to add a new profile, or check the box in the row of an existing profile and click EEdit.STEP 3 If creating a new profile, enter a unique name to identify the profile.STEP 4 In the SSID field, enter a unique name for this wireless network. Include up to 32 characters, using any of the characters on the keyboard. For added security, you should change the default value to a unique name.STEP 5 Check the BBroadcast SSID box if you want to allow all wireless clients within range to be able to detect this wireless network when they are scanning the local area for available networks. Disable this feature if you do not want to make the SSID known. When this feature is disabled, wireless users can connect to your wireless network only if they know the SSID (and provide the required security credentials).
Configuring the Wireless NetworkConfiguring Wireless ProfilesCisco RV 120W Administration Guide 643 STEP 6 In the Security field, select the type of security. All devices on your network must use the same security mode and settings to work correctly. Cisco recommends using the highest level of security that is supported by the devices in your network. •Disabled—Any device can connect to the network. Not recommended.•Wired Equivalent Privacy (WEP)— Weak security with a basic encryption method that is not as secure as WPA. WEP may be required if your network devices do not support WPA; however, it is not recommended. •Wi-Fi Protected Access (WPA) Personal—WPA is part of the wireless security standard (802.11i) standardized by the Wi-Fi Alliance and was intended as an intermediate measure to take the place of WEP while the 802.11i standard was being prepared. It supports TKIP/AES encryption. The personal authentication is the preshared key (PSK) that is an alphanumeric passphrase shared with the wireless peer.•WPA Enterprise—Allows you to use WPA with RADIUS server authentication.•WPA2 Personal—WPA2 is the implementation of security standard specified in the final 802.11i standard. It supports AES encryption and this option uses preshared key (PSK) based authentication. •WPA2 Personal Mixed—Allows both WPA and WPA2 clients to connect simultaneously using PSK authentication.•WPA2 Enterprise—Allows you to use WPA2 with RADIUS server authentication.•WPA2 Enterprise Mixed—Allows both WPA and WPA2 clients to connect simultaneously using RADIUS authentication. STEP 7 Perform the following steps based on the type of encryption you chose in Step 6:WPA/WPA2a. Select the encryption method to be used: TTKIP, AAES, or TTKIP+AES.b. Select the authentication method to be used: RRADIUS, PPSK, or PPSK + RADIUS. c. WPA Password—Enter the pre-shared key for WPA/WPA2 PSK authentication. The clients also need to be configured with the same password.d. (Optional) Check the Enable Pre-Authentication box to enable pre-authentication for this profile. Pre-authentication allows wireless clients to quickly switch between connected Access Points sharing the same security configuration. This is mainly used when APs are configured with WPA/WPA2
Configuring the Wireless NetworkConfiguring Wireless ProfilesCisco RV 120W Administration Guide 653 security. In event of wireless client disconnecting from an AP, a notification is sent to the AP, which then sends the pre-authentication info to other APs in the network. WEPIn the WEP Index and Keys section:a. In the Authentication field, choose OOpen System or SShared Key. If you choose open system, a wireless client doesn't need to provide a shared key in order to access the wireless network. Any client can associate to the router. If you choose shared key, a wireless client must provide the correct shared key (password) in order to access the wireless network.b. Select the encryption type (664- or 1128-bit). The larger size keys provide stronger encryption, making the key more difficult to crack (for example, 64-bit WEP has a 40-bit key which is less secure than the 128-bit WEP, which has a 104-bit key). c. (Optional) In the passphrase field, enter an alphanumeric phrase (longer than eight characters for optimal security) and click GGenerate Key to generate four unique WEP keys in the WEP Key fields below. d. Select one of the four to use as the shared key that devices must have in order to use the wireless network. If you did not generate a key in Step C, enter a key directly into the WEP Key field. The length of the key should be 5 ASCII characters (or 10 hexadecimal characters) for 64-bit WEP and 13 ASCII characters (or 26 hexadecimal characters) for 128-bit WEP. Valid hexadecimal characters are “0” to “9” and “A” to “F”.STEP 8 Click SSave.Configuring the Group Key Refresh IntervalIf you configure WPA or WPA2 security, you can specify the timeout interval after which group keys are generated:STEP 1 Choose WWireless > AAP Profile.STEP 2 Check the box in the row of the profile you want to configure and click AAdvanced Configuration.STEP 3 Enter the group key refresh interval, in seconds.

Configuring the Wireless Radio PropertiesYou can configure radio card properties, including the wireless standard (for example, 802.11n or 802.11g) on the Cisco RV 120W.Configuring Basic Wireless Radio SettingsSTEP 1 Choose WWireless > RRadio Settings > RRadio Settings.STEP 2 Select the WWireless Network Mode:•B/G Mixed—Select this mode if you have devices in the network that support 802.11b.•G Only—Select this mode if all devices in the wireless network only support 802.11g.•N/G Mixed—Select this mode if you have devices in the network that support 802.11g and 802.11n.•N Only—Select this mode if all devices in the wireless network support 802.11n. STEP 3 Select the channel bandwidth. Available choices depend on the wireless network mode chosen in Step 2.STEP 4 The control sideband field defines the sideband which is used for the secondary or extension channel when the AP is operating in 40 Mhz channel width. Choose lower or uupper. This field is only available when channel spacing is set to aauto. The signal components above the carrier frequency constitute the upper sideband (USB) and those below the carrier frequency constitute the lower sideband (LSB).STEP 5 The channel field specifies the frequency that the radio uses to transmit wireless frames. Select a channel from the list of channels or choose aauto to let the Cisco RV 120W determine the best channel to use based on the environment noise levels for the available channels.STEP 6 Click SSave..
Configuring the Wireless NetworkConfiguring the Wireless Radio PropertiesCisco RV 120W Administration Guide 713 Configuring Advanced Wireless Radio SettingsSTEP 1 Choose WWireless > RRadio Settings > RRadio Settings.STEP 2 In the beacon interval field, enter the time in milliseconds between beacon transmissions. The default interval is 100 milliseconds.STEP 3 In the DTIM interval field, enter the interval at which the delivery traffic indication message should be sent. A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the Cisco RV 120W has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast messages.The default interval is 2 beacon intervals. STEP 4 The Request to Send (RTS) threshold is the packet size, in bytes, that requires the AP to check the transmitting frames to determine if an RTS/Clear to Send (CTS) handshake is required with the receiving client. Using a small value causes RTS packets to be sent more often, consuming more of the available bandwidth, reducing the apparent throughput of the network packets. The default value is 2346, which effectively disables RTS. STEP 5 The fragmentation threshold is the maximum length of the frame, in bytes, beyond which packets must be fragmented into two or more frames. Collisions occur more often for long frames because while sending them, they occupy the channel for a longer time. The default value is 2346, which effectively disables fragmentation. If you experience a high packet error rate, you can slightly increase the fragmentation threshold; setting the fragmentation threshold too low may result in poor network performance. Only minor reduction of the default value is recommended.STEP 6 Choose the preamble mode. The 802.11b standard requires that a preamble be appended to every frame before it is transmitted through the air. The preamble may be either the traditional “long” preamble, which requires 192 Ðs for transmission, or it may be an optional “short” preamble that requires only 96 Ðs. A long preamble is needed for compatibility with the legacy 802.11 systems operating at 1 and 2 Mbps. The default selection is long.STEP 7 Choose the protection mode. Select nnone (the default) to turn off CTS. The CTS-to-Self Protection option enables the CTS-to-Self protection mechanism, which is used to minimize collisions among stations in a mixed 802.11b and 802.11g environment. This function boosts the Cisco RV 120W’s ability to catch all wireless transmissions but severely decreases performance.

4Cisco RV 120W Administration Guide 74 Configuring the FirewallThis chapter contains information about configuring the firewall properties of the Cisco RV 110W and includes the following sections:•Cisco RV 110W Firewall Features, page 74•Configuring Basic Firewall Settings, page 76•Configuring Firewall Rules, page 79•Creating Firewall Schedules, page 85•Blocking and Filtering Content and Applications, page 85•Firewall Rule Examples, page 90•Configuring Port Triggering, page 92•Configuring Port Forwarding, page 94•Configuring Remote Management, page 98•Configuring One-to-One Network Address Translation (NAT), page 99Cisco RV 110W Firewall FeaturesYou can secure your network by creating and applying rules that the Cisco RV 120W uses to selectively block and allow inbound and outbound Internet traffic. You then specify how and to what devices the rules apply. To do so, you must define the following:•Services or traffic types (examples: web browsing, VoIP, other standard services and also custom services that you define) that the router should allow or block.•Direction for the traffic by specifying the source and destination of traffic; this is done by specifying the “From Zone” (LAN/WAN/DMZ) and “To Zone” (LAN/WAN/DMZ).
Configuring the FirewallCisco RV 110W Firewall FeaturesCisco RV 120W Administration Guide 754 •Schedules as to when the router should apply rules.•Keywords (in a domain name or on a URL of a web page) that the router should allow or block.•Rules for allowing or blocking inbound and outbound Internet traffic for specified services on specified schedules.•MAC addresses of devices whose inbound access to your network the router should block.•Port triggers that signal the router to allow or block access to specified services as defined by port number.•Reports and alerts that you want the router to send to you.You can, for example, establish restricted-access policies based on time-of-day, web addresses, and web address keywords. You can block Internet access by applications and services on the LAN, such as chat rooms or games. You can block just certain groups of PCs on your network from being accessed by the WAN or public DMZ network.Inbound (WAN to LAN/DMZ) rules restrict access to traffic entering your network, selectively allowing only specific outside users to access specific local resources. By default, all access from the insecure WAN side is blocked from accessing the secure LAN, except in response to requests from the LAN or DMZ. To allow outside devices to access services on the secure LAN, you must create a firewall rule for each service.If you want to allow incoming traffic, you must make the router's WAN port IP address known to the public. This is called “exposing your host.” How you make your address known depends on how the WAN ports are configured; for the Cisco RV 120W, you may use the IP address if a static address is assigned to the WAN port, or if your WAN address is dynamic, a DDNS (Dynamic DNS) name can be used.Outbound (LAN/DMZ to WAN) rules restrict access to traffic leaving your network, selectively allowing only specific local users to access specific outside resources. The default outbound rule is to allow access from the secure zone (LAN) to either the public DMZ or insecure WAN. To block hosts on the secure LAN from accessing services on the outside (insecure WAN), you must create a firewall rule for each service.
Configuring the FirewallConfiguring Basic Firewall SettingsCisco RV 120W Administration Guide 764 Configuring Basic Firewall SettingsTo configure basic firewall settings, choose FFirewall > BBasic Settings. You can configure the following:Protecting from AttacksAttacks are malicious security breeches or unintentional network issues that render the Cisco RV 120W unusable. Attack checks allow you to manage WAN security threats such as continual ping requests and discovery via ARP scans. TCP and UDP flood attack checks can be enabled to manage extreme usage of WAN resources. As well, certain Denial-of-Service (DoS) attacks can be blocked. These attacks, if uninhibited, can use up processing power and bandwidth and prevent regular network services from running normally. ICMP packet flooding, SYN traffic flooding, and Echo storm thresholds can be configured to temporarily suspect traffic from the offending source. STEP 1 Choose FFirewall > BBasic Settings > AAttack Checks.STEP 2 Check the boxes to enable the following functions: WAN Security•Respond to Ping on the Internet—To configure the Cisco RV 120W to allow a response to an Internet Control Message Protocol (ICMP) Echo (ping) request on the WAN interface, check this box. This setting is used as a diagnostic tool for connectivity problems. Not enabled by default.•Enable Stealth Mode—If Stealth Mode is enabled, the router will not respond to port scans from the WAN. This feature makes the network less susceptible to discovery and attacks. Enabled by default.•Block TCP Flood— If this option is enabled, the router will drop all invalid TCP packets. This feature protects the network from a SYN flood attack. Enabled by default.LAN Security •Block UDP Flood—If this option is enabled, the router will not accept more than 25 simultaneous, active UDP connections from a single computer on the LAN. Enabled by default.

See Creating Firewall Schedules, page 85.STEP 7 In the SSource Hosts field, select the users to which the firewall rule applies:•Any—The rule applies to traffic originating on any host in the local network.•Single Address—The rule applies to traffic originating on a single IP address in the local network. Enter the address in the From field.•Address Range—The rule applies to traffic originating from an IP address located in a range of addresses. Enter the starting IP address in the FFrom field, and the ending IP address in the TTo field.STEP 8 In the LLog field, specify whether or not the packets for this rule should be logged. To log details for all packets that match this rule, select AAlways. For example, if an outbound rule for a schedule is selected as BBlock Always, then for every packet that tries to make an outbound connection for that service, a message with the packet’s source address and destination address (and other information) is recorded in the log. Enabling logging may generate a significant volume of log messages and is recommended for debugging purposes only. Select NNever to disable logging. STEP 9 When traffic is going from the LAN or DMZ to the WAN, the system requires rewriting the source or destination IP address of incoming IP packets as they pass through the firewall. In the SNAT IP Type field, choose WWAN Interface Address or choose Single Address and enter the Single IP Address in the SNAT IP field.STEP 10 In the QQoS Priority field, assign a priority to IP packets of this service. The priorities are defined by “Type of Service (TOS) in the Internet Protocol Suite” standards, RFC 1349. The gateway marks the Type Of Service (TOS) field as defined below:•Normal-Service—No special priority is given to the traffic. The IP packets for services with this priority are marked with a TOS value of 0.
Configuring the FirewallConfiguring Firewall RulesCisco RV 120W Administration Guide 834 •Minimize-Cost—Choose this option when data must be transferred over a link that has a lower “cost.” The IP packets for services with this priority are marked with a TOS value of 2. •Maximize-Reliability—Choose this option when data needs to travel to the destination over a reliable link and with little or no retransmission. The IP packets for services with this priority are marked with a TOS value of 4. •Maximize-Throughput—Choose this option when the volume of data transferred during an interval is important even if the latency over the link is high. The IP packets for services with this priority are marked with a TOS value of 8. •Minimize-Delay—Choose this option when the time required (latency) for the packet to reach the destination must be low. The IP packets for services with this priority are marked with a TOS value of 16.STEP 11 When the traffic is coming from the WAN to the DMZ or the LAN, Destination Network Address Translation maps a public IP address (your Dedicated WAN address, Optional WAN address, or another address) to an IP address on your private network. Enter the following:•Send to Local Server (DNAT IP)—Specify an IP address of a machine on the Local Network which is hosting the server. •(Optional) Check the EEnable Port Forwarding box to enable port forwarding to the port that you specify in the Translate Port Number field. This will allow traffic from the Internet to reach the appropriate LAN port via a port forwarding rule.•Translate Port Number—Enter the port number to use for port forwarding. For example, if a machine on the Local Network side is running a telnet server on port 2000, then check the EEnable Port Forwarding box and enter 2000 in the Translate Port Number field. If the server is listening on the default port 23, then the box can be left unchecked.•Internet Destination Address—Select the public IP address that is used for this firewall rule: Dedicated WAN, Optional WAN, or Other. If you choose Other, enter the WAN IP address that will map to the internal server in the Other IP Address field.
Configuring the FirewallConfiguring Firewall RulesCisco RV 120W Administration Guide 844 This gateway supports multi-NAT, and the Internet Destination IP address does not necessarily have to be the WAN address. On a single WAN interface, multiple public IP addresses are supported. If your ISP assigns you more than one public IP address, one of these can be used as your primary IP address on the WAN port, and the others can be assigned to servers on the LAN or DMZ. In this way, the LAN/DMZ server can be accessed from the internet by its aliased public IP address.

You can block access to Internet sites by specifying keywords to block. If these keywords are found in the site's name (for example, web site URL or newsgroup name), the site is blocked.
Configuring the FirewallBlocking and Filtering Content and ApplicationsCisco RV 120W Administration Guide 864 You also need to turn on content filtering to set up trusted domains.Blocking Web Applications and ComponentsSTEP 1 Choose FFirewall > AAccess Control > CContent Filtering.STEP 2 Check the EEnable box.STEP 3 Certain commonly-used web components can be blocked for increased security. Some of these components can be used by malicious websites to infect computers that access them. With content filtering enabled, select the check box for each component you wish to block: •Proxy—A proxy server (or simply, proxy) allows computers to route connections to other computers through the proxy, thus circumventing certain firewall rules. For example, if connections to a specific IP address are blocked by a firewall rule, the requests can be routed through a proxy that is not blocked by the rule, rendering the restriction ineffective. Enabling this feature blocks proxy servers.•Java—Blocks java applets from being downloaded from pages that contain them. Java applets are small programs embedded in web pages that enable dynamic functionality of the page. A malicious applet can be used to compromise or infect computers. Enabling this setting blocks Java applets from being downloaded.•ActiveX—Similar to Java applets, ActiveX controls are installed on a Windows computer while running Internet Explorer. A malicious ActiveX control can be used to compromise or infect computers. Enabling this setting blocks ActiveX applets from being downloaded.

Keywords prevent access to websites that contain the specified characters in the URL or the page contents.STEP 4 Select the group to which to apply the keyword blocking. (These groups are configured in the NNetworking > LLAN > LLAN Groups page.)STEP 5 Click SSave.Configuring MAC Address FilteringMAC address filtering allows you to block traffic coming from certain known machines or devices. The router uses the MAC address of a computer or device on the network to identify it and block or permit the access. Traffic coming in from a specified MAC address will be filtered depending upon the policy. To enable MAC address filtering:STEP 1 Choose FFirewall > AAccess Control > MMAC Filtering.STEP 2 Check the EEnable box to enable MAC Address Filtering for this device. Uncheck the box to disable this feature.If you enable MAC filtering, in the Policy for MAC Address listed below field, choose one of the following options: •Block and Permit the rest—Choose this option to block the traffic from the specified MAC addresses and to allow traffic from all other addresses.•Permit and Block the rest—Choose this option to permit the traffic from the specified MAC addresses and to block traffic from all other machines on the LAN side of the router.For example, two computers are on the LAN with MAC addresses of 00:01:02:03:04:05 (host1), and 00:01:02:03:04:11 (host2). If the host1 MAC address is added to the MAC filtering list and the “block and permit the rest” policy is chosen, when this computer tries to connect to a website, the router will not allow
Configuring the FirewallBlocking and Filtering Content and ApplicationsCisco RV 120W Administration Guide 894 it to connect. However, host2 is able to connect because its MAC address is not in the list. If the policy is “permit and block the rest,” then host1 is able to connect to a website, but host2 is blocked because its URL is not in the list. The MAC filtering policy does not override a firewall rule that directs incoming traffic to a host. STEP 3 Click SSave.STEP 4 In the MAC Addresses table, click AAdd. STEP 5 Enter the MAC address to add to the table and click SSave. Repeat for each address to permit or block.Configuring IP/MAC Address BindingIP/MAC Binding allows you to bind IP addresses to MAC address. Some machines are configured with static addresses. To prevent users from changing static IP addresses, IP/MAC Binding should be enabled. If the Cisco RV 110W sees packets with matching IP address but inconsistent MAC addresses, it drops those packets.To configure IP/MAC Address binding:STEP 1 Choose FFirewall > AAccess Control > IIP/MAC Binding. The table lists all the currently defined IP/MAC binding rules and allows several operations on the rules. STEP 2 Click AAdd to add a new rule.STEP 3 In the name field, enter the name for this rule. STEP 4 In the MAC Addresses field, enter the MAC Addresses (the physical address of the piece of hardware) for this rule. STEP 5 In the IP Addresses field, enter the IP Addresses to assign to the piece of hardware. STEP 6 In the Log Dropped Packets field, choose if you want to log the dropped packets. Choosing eenable logs the dropped packets. Logs can be viewed in Status > VView All Logs page.

Configuring the FirewallFirewall Rule ExamplesCisco RV 120W Administration Guide 914 Example 3: Multi-NAT Configuration In this example, you want to configure multi-NAT to support multiple public IP addresses on one WAN port interface.Create an inbound rule that configures the firewall to host an additional public IP address. Associate this address with a web server on the DMZ. If you arrange with your ISP to have more than one public IP address for your use, you can use the additional public IP addresses to map to servers on your LAN. One of these public IP addresses is used as the primary IP address of the router. This address is used to provide Internet access to your LAN PCs through NAT. The other addresses are available to map to your DMZ servers.The following addressing scheme is used to illustrate this procedure:•WAN IP address: 10.1.0.118• LAN IP address: 192.168.1.1; subnet 255.255.255.0• Web server PC in the DMZ, IP address: 192.168.1.2• Access to Web server: (simulated) public IP address 10.1.0.52Action Allow alwaysSend to Local Server (DNAT IP) 192.168.1.11Destination Users Address RangeFrom 132.177.88.2To 134.177.88.254Enable Port Forwarding Yes (enabled)Parameter ValueParameter ValueFrom Zone Insecure (WAN1/WAN2)To Z o n e P u b l i c ( D M Z )Service HTTPAction Allow always

Choose FFirewall > AAccess Control > SSchedules.STEP 2 Enter WWeekend in the Name field.STEP 3 Under SScheduled Days, choose SSpecific Days.STEP 4 Check the box next to Saturday and Sunday.STEP 5 Under SScheduled Time of Day, select AAll Day. This applies the schedule from 12:00 a.m. to 11:59 p.m. of the selected days.STEP 6 Click SSave.Configuring Port TriggeringPort triggering allows devices on the LAN or DMZ to request one or more ports to be forwarded to them. Port triggering waits for an outbound request from the LAN/DMZ on one of the defined outgoing ports, and then opens an incoming port for that specified type of traffic. Port triggering is a form of dynamic port forwarding while an application is transmitting data over the opened outgoing or incoming ports.Send to Local Server (DNAT IP) 192.168.1.2 (local IP address of your web server)Destination Users Single AddressFrom 10.1.0.52WAN Users AnyLog NeverParameter Value
Configuring the FirewallConfiguring Port TriggeringCisco RV 120W Administration Guide 934 Port triggering opens an incoming port for a specific type of traffic on a defined outgoing port. Port triggering is more flexible than static port forwarding (available when configuring firewall rules) because a rule does not have to reference a specific LAN IP or IP range. Ports are also not left open when not in use, thereby providing a level of security that port forwarding does not offer. NOTE Port triggering is not appropriate for servers on the LAN, since there is a dependency on the LAN device making an outgoing connection before incoming ports are opened. Some applications require that, when external devices connect to them, they receive data on a specific port or range of ports in order to function properly. The router must send all incoming data for that application only on the required port or range of ports. The gateway has a list of common applications and games with corresponding outbound and inbound ports to open. You can also specify a port triggering rule by defining the type of traffic (TCP or UDP) and the range of incoming and outgoing ports to open when enabled. To add a port triggering rule:STEP 1 Choose FFirewall > PPort Triggering.STEP 2 Click AAdd.STEP 3 Specify an easily-identifiable name for this rule. STEP 4 Check the EEnable box to enable the rule. STEP 5 Select whether the port uses TCP or UDP protocol. STEP 6 In the OOutgoing (Trigger) Port Range section, specify the port number or range of port numbers that will trigger this rule when a connection request from outgoing traffic is made. If the outgoing connection uses only one port, then specify the same port number in the Start Port and End Port fields. STEP 7 In the IIncoming (Response) Port Range section, specify the port number or range of port numbers used by the remote system to respond to the request it receives. If the incoming connection uses only one port, then specify the same port number in the Start Port and End Port fields.STEP 8 Click SSave.
Configuring the FirewallConfiguring Port ForwardingCisco RV 120W Administration Guide 944 Configuring Port ForwardingPort forwarding is used to redirect traffic from the Internet from one port on the WAN to another port on the LAN. The port forwarding rules menu allows selection of a service. Common services are available or you can define a custom service and associated ports to forward. The Port Forwarding Rules table lists all the available port forwarding rules for this device and allows you to configure port forwarding rules. The table contains the following information:•Status—A port forwarding rule can be disabled if not in use and enabled when needed. The port forwarding rule is disabled if the status is disabled and it is enabled if the status is enabled. Disabling a port forwarding rule does not delete the configuration. •Service—Service for which this port forwarding rule is applicable.•Action—Whether to block or allow traffic (always or by schedule) that meets these filter rules, and when the rule is applicable. •Source Users—The source IP for this port forwarding rule (Any, Single, Range, or Host name).•Local Server—The DNAT IP address, if traffic that meets this filter rule is sent to a local server. •Internet Destination—Which of the WAN ports (if more than one is available) that is the Internet destination for traffic covered by this port forwarding rule.•Log—Whether this port forwarding rule is logged (always or never).To configure port forwarding:STEP 1 Choose FFirewall > PPort Forwarding.STEP 2 Click AAdd.STEP 3 Under SService, select one of the common or custom services defined for this device:•AIM (AOL Instant Messenger)•BGP (Border Gateway Control)•BOOT_P (Bootstrap Protocol) client

Configuring Virtual Private Networks (VPNs) and SecurityConfiguring VPNsCisco RV 120W Administration Guide 1025 Configuring VPNsA VPN provides a secure communication channel (“tunnel”) between two gateway routers or a remote PC client and a gateway router. The following types of tunnels can be created:•Gateway-to-gateway VPN—Connects two or more routers to secure traffic between remote sites. •Remote Client (client-to-gateway VPN tunnel)—A remote client initiates a VPN tunnel. The IP address of the remote PC client is not known in advance. The gateway acts as responder.•Remote client behind a NAT router—The client has a dynamic IP address and is behind a NAT Router. The remote PC client at the NAT router initiates a VPN tunnel. The IP address of the remote NAT router is not known in advance. The gateway WAN port acts as a responder.Creating Cisco QuickVPN Client UsersTo use the Cisco QuickVPN, you must do the following:STEP 1 Enable remote management. See Configuring Remote Management, page 98.STEP 2 Create QuickVPN users. See Configuring IPsec Users, page 114. After a user account is created, the credentials can be used by the QuickVPN client.For more information on installing and using Cisco QuickVPN, see Appendix A, “Using Cisco QuickVPN for Windows 2000, XP, or Vista.”Using the VPN WizardYou can use the VPN wizard to quickly create both IKE and VPN policies.

Configuring Virtual Private Networks (VPNs) and SecurityConfiguring VPNsCisco RV 120W Administration Guide 1125 Auto Policy Parameters STEP 1 SA Lifetime—Enter the duration of the Security Association and choose the unit from the drop-down list:•Seconds—Choose this option to measure the SA Lifetime in seconds. After the specified number of seconds passes, the Security Association is renegotiated. The default value is 3600 seconds. The minimum value is 300 seconds.•Kbytes—Choose this option to measure the SA Lifetime in kilobytes. After the specified number of kilobytes of data is transferred, the SA is renegotiated. The minimum value is 1920000 KB.NOTE When configuring a Lifetime in kilobytes (also known as lifebytes), be aware that two SAs are created for each policy. One SA applies to inbound traffic, and one SA applies to outbound traffic. Due to differences in the upstream and downstream traffic flows, the SA may expire asymmetrically. For example, if the downstream traffic is very high, the lifebyte for a download stream may expire frequently. The lifebyte of the upload stream may not expire as frequently. It is recommended that the values be reasonably set, to reduce the difference in expiry frequencies of the SAs; otherwise the system may eventually run out of resources as a result of this asymmetry. The lifebyte specifications are generally recommended for advanced users only. STEP 2 Select the algorithm used to encrypt the data. STEP 3 Select the algorithm used to verify the integrity of the data. STEP 4 Check the PPFS Key Group box to enable Perfect Forward Secrecy (PFS) to improve security. While slower, this protocol helps to prevent eavesdroppers by ensuring that a Diffie-Hellman exchange is performed for every phase-2 negotiation. STEP 5 Choose the IKE policy that will define the characteristics of phase 1 of the negotiation.
Configuring Virtual Private Networks (VPNs) and SecurityConfiguring VPNsCisco RV 120W Administration Guide 1135 Configuring VPN ClientsVPN clients must be configured with the same VPN policy parameters used in the VPN tunnel the client wishes to use: encryption, authentication, life time, and PFS key-group. Upon establishing these authentication parameters, the VPN Client user database must also be populated with an account to give a user access to the tunnel. VPN client software is required to establish a VPN tunnel between the router and remote endpoint. Open source software (such as OpenVPN or Openswan) as well as Microsoft IPsec VPN software can be configured with the required IKE policy parameters to establish an IPsec VPN tunnel. Refer to the client software guide for detailed instructions on setup as well as the router’s online help. The user database contains the list of VPN user accounts that are authorized to use a given VPN tunnel. Alternatively VPN tunnel users can be authenticated using a configured RADIUS database. Refer to the online help to determine how to populate the user database and/or configure RADIUS authentication. Monitoring VPN Tunnel StatusYou can view and change the status of (connect or drop) the router’s IPsec security associations. The VPN tunnel status can be found in the SStatus > IIPsec Connection Status page. Here the active IPsec SAs (security associations) are listed along with the traffic details and tunnel state. The traffic is a cumulative measure of transmitted/received packets since the tunnel was established. If a VPN policy state is “not connected”, it can be enabled from the List of VPN Policies in the VVPN > IIPsec > IIPsec Policies page.

Configuring Virtual Private Networks (VPNs) and SecurityConfiguring SecurityCisco RV 120W Administration Guide 1155 Configuring VPN PassthroughVPN passthrough allows VPN traffic that originates from VPN clients to pass through the router. For example, if you are not using a VPN that is configured on the Cisco RV 110W, but are using a laptop to access a VPN at another site, configuring VPN passthrough allows that connection.To configure VPN passthrough:STEP 1 Choose VVPN > VVPN Passthrough.STEP 2 Choose the type of traffic to allow to pass through the router:•IPsec—Check EEnable to allow IP security tunnels to pass through the router.•PPTP—Check EEnable to allow Point-to-Point Tunneling Protocol tunnels to pass through the router.•L2TP—Check EEnable to allow Layer 2 Tunneling Protocol tunnels to pass through the router.STEP 3 Click SSave.Configuring SecurityThe Cisco RV 110W provides several security methods, including certificate authentication, RADIUS server support, and 802.1x port-based authentication.Using Certificates for AuthenticationThe Cisco RV 110W uses digital certificates for IPsec VPN authentication and SSL validation (for HTTPS and SSL VPN authentication). You can obtain a digital certificate from a well-known Certificate Authority (CA) such as VeriSign, or generate and sign your own certificate using functionality available on this gateway. The gateway comes with a self-signed certificate, and this can be replaced by one signed by a CA as per your networking requirements. A CA certificate provides strong assurance of the server's identity and is a requirement for most corporate network VPN solutions.
Configuring Virtual Private Networks (VPNs) and SecurityConfiguring SecurityCisco RV 120W Administration Guide 1165 The certificates menu allows you to view a list of certificates (both from a CA and self-signed) currently loaded on the gateway. The following certificate data is displayed in the list of Trusted (CA) certificates: •CA Identity (Subject Name)—The certificate is issued to this person or organization.•Issuer Name—The name of the Certificate Authority that issued this certificate.•Expiry Time—The date after which this Trusted certificate becomes invalid.A self certificate is a certificate issued by a CA identifying your device (or self-signed if you don't want the identity protection of a CA). The Active Self Certificate table lists the self certificates currently loaded on the gateway. The following information is displayed for each uploaded self certificate:•Name—The name you use to identify this certificate. It is not displayed to IPsec VPN peers or SSL users.•Subject Name—This is the name that is displayed as the owner of this certificate. This should be your official registered or company name, as IPsec or SSL VPN peers are shown this field. •Serial Number—The serial number is maintained by the CA and used to identify this signed certificate.•Issuer Name—This is the CA name that issued (signed) this certificate•Expiry Time—The date after which this signed certificate becomes invalid - you should renew the certificate before it expires.To request a self certificate to be signed by a CA, you can generate a Certificate Signing Request from the gateway by entering identification parameters and sending to the CA for signing. Once signed, the CA's Trusted Certificate and signed certificate from the CA are uploaded to activate the self-certificate validating the identity of this gateway. The self certificate is then used in IPsec and SSL connections with peers to validate the gateway's authenticity. To configure certificates, choose SSecurity > AAuthentication (Certificates).

6Cisco RV 120W Administration Guide 120 Configuring Quality of Service (QoS)The Cisco RV 110W provides configuration for QoS features, such as bandwidth profiles, traffic selectors, and traffic meters. It contains the following sections:•Configuring Bandwidth Profiles, page 120•Configuring Traffic Flows, page 121•Configuring Traffic Metering, page 122•Configuring 802.1p, page 124Configuring Bandwidth ProfilesUsing bandwidth profiles, the bandwidth of the traffic flowing from the secure network (LAN) to the insecure network (WAN) can be shaped. Bandwidth limiting determines the speed from which the data is sent from your router. You can use a bandwidth profile to limit the outbound traffic, thus preventing the LAN users from consuming all of the bandwidth of the Internet link. Bandwidth profiles configuration consists of enabling the bandwidth control feature from the Device Manager, and adding a profile which defines the control parameters. The profile can then be associated with a traffic selector, so that bandwidth profile can be applied to the traffic matching the selectors. To configure bandwidth profiles, perform the following steps.Enable Bandwidth ProfilesSTEP 1 Choose QQoS > BBandwidth Profiles.STEP 2 Check the EEnable box.STEP 3 Click SSave.

To configure traffic metering:STEP 1 Choose QQoS > TTraffic Meter.STEP 2 Check the EEnable box to enable traffic metering on the optional WAN port. The router will keep a record of the volume of traffic going from this interface. The router can also be configured to place a restriction on the volume of data being transferred. STEP 3 Choose the TTraffic Limit type:•No Limit—The default option, where no limits on data transfer are imposed. Choosing this option displays the outgoing and incoming traffic volume in the Internet Traffic Statistics section on the page. If traffic metering is not enabled, these statistics are not shown. •Download Only—Limits the amount of download traffic. Enter the maximum allowed data (in Megabytes) that can be downloaded for a given month in the MMonthly Limit field. Once the limit is reached, no traffic will be allowed from the WAN side. •Both Directions—For this setting, the router will calculate traffic for both upload and download directions. The traffic limit typed into the MMonthly Limit field is shared by both upload and download traffic. For example, for a 1GB limit, if a 700 MB file is downloaded then the remaining 300 MB must be shared between both upload and download traffic. The amount of traffic downloaded will reduce the amount of traffic that can be uploaded and vice-versa. STEP 4 Enter the volume limit in the MMonthly Limit field that is applicable for this month. This limit will apply to the type of direction (Download Only or Both) selected above.

Administering Your Cisco RV 120WConfiguring LoggingCisco RV 120W Administration Guide 1327 Configuring Local LoggingThe router can be configured to log and e-mail notifications for denial of service attacks, general attack information, login attempts, dropped packets, etc. to a specified e-mail address or a Syslog server. Routing Logs This section is used to configure the logging options for each network segment (for example, LAN-WAN). NOTE Enabling logging options may generate a significant volume of log messages and is recommended for debugging purposes only. •AAccepted Packets—Check this box to log packets that were successfully transferred through the segment. This option is useful when the Default Outbound Policy is “Block Always” (see the FFirewall > IIPv4 Rules or IIPv6 Rules page). For example, if AAccept Packets from LAN to WAN is enabled and there is a firewall rule to allow ssh traffic from the LAN, then whenever a LAN machine tries to make an ssh connection, those packets will be accepted and a message will be logged. (Make sure the log option is set to allow for this firewall rule.) •Dropped Packets—Check this box to log packets that were blocked from being transferred through the segment. This option is useful when the Default Outbound Policy is “Allow Always” (see the FFirewall > IIPv4 Rules or IPv6 Rules page). For example, if Drop Packets from LAN to WAN is enabled and there is a firewall rule to block ssh traffic from LAN, then whenever a LAN machine tries to make an ssh connection, those packets will be dropped and a message will be logged. (Make sure the log option is set to allow for this firewall rule.) System Logs Select the type of system events to be logged. The following system events can be recorded: •All Unicast Traffic—Check this box to log all unicast packets directed to the router. •All Broadcast/Multicast Traffic—Check this box to log all broadcast or multicast packets directed to the router.
