140 Appendix A - Firewall STATEFUL PACKET INSPECTION Refers to an architecture, where the firewall keeps track of packets on each connection traversing all its interfaces and makes sure they are valid. This is in contrast to static packet filtering which only examines a packet based on the information in the packet header. DENIAL OF SERVICE ATTACK Is an incident in which a user or organization is deprived of the services of a resource they would normally expect to have. Various DoS attacks the device can withstand are ARP Attack, Ping Attack, Ping of Death, Land, SYN Attack, Smurf Attack, and Tear Drop. TCP/IP/PORT/INTERFACE FILTER These rules help in the filtering of traffic at the Network layer (i.e. Layer 3). When a Routing interface is created, Enable Firewall must be checked. Navigate to Advanced Setup  Security  IP Filtering. OUTGOING IP FILTER Helps in setting rules to DROP packets from the LAN interface. By default, if the Firewall is Enabled, all IP traffic from the LAN is allowed. By setting up one or more filters, specific packet types coming from the LAN can be dropped. Example 1: Filter Name : Out_Filter1 Protocol : TCP Source IP address : 192.168.1.45 Source Subnet Mask : 255.255.255.0 Source Port : 80 Dest. IP Address : NA Dest. Subnet Mask : NA Dest. Port : NA This filter will Drop all TCP packets coming from the LAN with IP Address/Subnet Mask of 192.168.1.45/24 having a source port of 80 irrespective of the destination. All other packets will be Accepted. Example 2: Filter Name : Out_Filter2 Protocol : UDP Source IP Address : 192.168.1.45 Source Subnet Mask : 255.255.255.0 Source Port : 5060:6060 Dest. IP Address : 172.16.13.4 Dest. Subnet Mask : 255.255.255.0 Dest. Port : 6060:7070 This filter will drop all UDP packets coming from the LAN with IP Address / Subnet Mask of 192.168.1.45/24 and a source port range of 5060 to 6060, destined to 172.16.13.4/24 and a destination port range of 6060 to 7070. INCOMING IP FILTER Helps in setting rules to Allow or Deny packets from the WAN interface. By default, all incoming IP traffic from the WAN is Blocked, if the Firewall is Enabled. By setting up one or more filters, specific packet types coming from the WAN can be Accepted.
141 Example 1: Filter Name : In_Filter1 Protocol : TCP Policy : Allow Source IP Address : 210.168.219.45 Source Subnet Mask : 255.255.0.0 Source Port : 80 Dest. IP Address : NA Dest. Subnet Mask : NA Dest. Port : NA Selected WAN interface : br0 This filter will ACCEPT all TCP packets coming from WAN interface “br0” with IP Address/Subnet Mask 210.168.219.45/16 with a source port of 80, irrespective of the destination. All other incoming packets on this interface are DROPPED. Example 2: Filter Name : In_Filter2 Protocol : UDP Policy : Allow Source IP Address : 210.168.219.45 Source Subnet Mask : 255.255.0.0 Source Port : 5060:6060 Dest. IP Address : 192.168.1.45 Dest. Sub. Mask : 255.255.255.0 Dest. Port : 6060:7070 Selected WAN interface : br0 This rule will ACCEPT all UDP packets coming from WAN interface “br0” with IP Address/Subnet Mask 210.168.219.45/16 and a source port in the range of 5060 to 6060, destined to 192.168.1.45/24 and a destination port in the range of 6060 to 7070. All other incoming packets on this interface are DROPPED. MAC LAYER FILTER These rules help in the filtering of Layer 2 traffic. MAC Filtering is only effective in Bridge mode. After a Bridge mode connection is created, navigate to Advanced Setup  Security  MAC Filtering in the WUI. Example 1: Global Policy : Forwarded Protocol Type : PPPoE Dest. MAC Address : 00:12:34:56:78:90 Source MAC Address : NA Src. Interface : eth1 Dest. Interface : eth2 Addition of this rule drops all PPPoE frames going from eth1 to eth2 with a Destination MAC Address of 00:12:34:56:78:90 irrespective of its Source MAC Address. All other frames on this interface are forwarded. Example 2: Global Policy : Blocked Protocol Type : PPPoE Dest. MAC Address : 00:12:34:56:78:90 Source MAC Address : 00:34:12:78:90:56 Src. Interface : eth1 Dest. Interface : eth2 Addition of this rule forwards all PPPoE frames going from eth1 to eth2 with a Destination MAC Address of 00:12:34:56:78 and Source MAC Address of 00:34:12:78:90:56. All other frames on this interface are dropped.
142 DAYTIME PARENTAL CONTROL This feature restricts access of a selected LAN device to an outside Network through the NexusLink 3112u , as per chosen days of the week and the chosen times. Example: User Name : FilterJohn Browser's MAC Address : 00:25:46:78:63:21 Days of the Week : Mon, Wed, Fri Start Blocking Time : 14:00 End Blocking Time : 18:00 With this rule, a LAN device with MAC Address of 00:25:46:78:63:21 will have no access to the WAN on Mondays, Wednesdays, and Fridays, from 2pm to 6pm. On all other days and times, this device will have access to the outside Network.

155 E2 ~ WAN Connections The NexusLink 3112u supports one WAN connection for each interface, up to a maximum of 16 connections. To setup a WAN connection follow these instructions. STEP 1: Go to Basic Setup  WAN Setup. STEP 2: Click Add to create a WAN connection. The following screen will display.
156 STEP 3: Choose a layer 2 interface from the drop-down box and click Next. The WAN Service Configuration screen will display as shown below. NOTE: The WAN services shown here are those supported by the layer 2 interface you selected in the previous step. If you wish to change your selection click the Back button and select a different layer 2 interface. STEP 4: For VLAN Mux Connections only, you must enter Priority & VLAN ID tags. STEP 5: You will now follow the instructions specific to the WAN service type you wish to establish. This list should help you locate the correct procedure: (1) For PPP over ETHERNET (PPPoE), go to page 157. (2) For IP over ETHERNET (IPoE), go to page 163. (3) For Bridging, go to page 168. (4) For PPP over ATM (PPPoA), go to page 170. (5) For IP over ATM (IPoA), go to page 175. The subsections that follow continue the WAN service setup procedure.
157 E2.1 PPP over ETHERNET (PPPoE) STEP 1: Select the PPP over Ethernet radio button and click Next. You can also enable IPv6 by ticking the checkbox  at the bottom of this screen. STEP 2: On the next screen, enter the PPP settings as provided by your ISP. Click Next to continue or click Back to return to the previous step.
158 The settings shown above are described below. PPP SETTINGS The PPP Username, PPP password and the PPPoE Service Name entries are dependent on the particular requirements of the ISP. The user name can be a maximum of 256 characters and the password a maximum of 32 characters in length. For Authentication Method, choose from AUTO, PAP, CHAP, and MSCHAP.
159 ENABLE FULLCONE NAT This option becomes available when NAT is enabled. Known as one-to-one NAT, all requests from the same internal IP address and port are mapped to the same external IP address and port. An external host can send a packet to the internal host, by sending a packet to the mapped external address. DIAL ON DEMAND The NexusLink 3112u can be configured to disconnect if there is no activity for a period of time by selecting the Dial on demand checkbox . You must also enter an inactivity timeout period in the range of 1 to 4320 minutes. PPP IP EXTENSION The PPP IP Extension is a special feature deployed by some service providers. Unless your service provider specifically requires this setup, do not select it. PPP IP Extension does the following: • Allows only one PC on the LAN. • Disables NAT and Firewall. • The device becomes the default gateway and DNS server to the PC through DHCP using the LAN interface IP address. • The device extends the IP subnet at the remote service provider to the LAN PC. i.e. the PC becomes a host belonging to the same IP subnet. • The device bridges the IP packets between WAN and LAN ports, unless the packet is addressed to the device’s LAN IP address. • The public IP address assigned by the remote side using the PPP/IPCP protocol is actually not used on the WAN PPP interface. Instead, it is forwarded to the PC LAN interface through DHCP. Only one PC on the LAN can be connected to the remote, since the DHCP server within the device has only a single IP address to assign to a LAN device. ENABLE NAT If the LAN is configured with a private IP address, the user should select this checkbox . The NAT submenu will appear in the Advanced Setup menu after reboot. On the other hand, if a private IP address is not used on the LAN side (i.e. the LAN side is using a public IP), this checkbox  should not be selected to free up system resources for better performance. ENABLE FIREWALL If this checkbox  is selected, the Security submenu will be displayed on the Advanced Setup menu after reboot. If firewall is not necessary, this checkbox  should not be selected to free up system resources for better performance. USE STATIC IPv4 ADDRESS Unless your service provider specially requires it, do not select this checkbox . If selected, enter the static IP address in the IPv4 Address field. Don’t forget to adjust the IP configuration to Static IP Mode as described in section 3.2.
160 FIXED MTU Maximum Transmission Unit. The size (in bytes) of largest protocol data unit which the layer can pass onwards. This value is 1500 for PPPoA. ENABLE PPP DEBUG MODE When this option is selected, the system will put more PPP connection information into the system log. This is for debugging errors and not for normal usage. BRIDGE PPPOE FRAMES BETWEEN WAN AND LOCAL PORTS (This option is hidden when PPP IP Extension is enabled) When Enabled, this creates local PPPoE connections to the WAN side. Enable this option only if all LAN-side devices are running PPPoE clients, otherwise disable it. The NexusLink 3112u supports pass-through PPPoE sessions from the LAN side while simultaneously running a PPPoE client from non-PPPoE LAN devices. ENABLE IGMP MULTICAST PROXY Tick the checkbox  to enable Internet Group Membership Protocol (IGMP) multicast. This protocol is used by IPv4 hosts to report their multicast group memberships to any neighboring multicast routers. NO MULTICAST VLAN FILTER Tick the checkbox  to Enable/Disable multicast VLAN filter. Enable WAN interface with base MAC Enable this option to use the router’s base MAC address as the MAC address for this WAN interface. STEP 3: Choose an interface to be the default gateway. Click Next to continue or click Back to return to the previous step.
161 Select DNS Server Interface from available WAN interfaces OR enter static DNS server IP addresses for the system. In ATM mode, if only a single PVC with IPoA or static IPoE protocol is configured, Static DNS server IP addresses must be entered. Click Next to continue or click Back to return to the previous step. STEP 5: The WAN Setup - Summary screen shows a preview of the WAN service you have configured. Check these settings and click Apply/Save if they are correct, or click Back to modify them.
162 After clicking Apply/Save, the new service should appear on the main screen. To activate it you must reboot. Go to Management  Reboot and click Reboot.
163 E2.2 IP over ETHERNET (IPoE) STEP 1: *Select the IP over Ethernet radio button and click Next. * For tagged service, enter valid 802.1P Priority and 802.1Q VLAN ID. For untagged service, set -1 to both 802.1P Priority and 802.1Q VLAN ID. STEP 2: The WAN IP settings screen provides access to the DHCP server settings. You can select the Obtain an IP address automatically radio button to enable DHCP (use the DHCP Options only if necessary). However, if you prefer, you can instead use the Static IP address method to assign WAN IP address, Subnet Mask and Default Gateway manually.
164 NOTE: If IPv6 networking is enabled, an additional set of instructions, radio buttons, and text entry boxes will appear at the bottom of the screen. These configuration options are quite similar to those for IPv4 networks. Click Next to continue or click Back to return to the previous step. STEP 3: This screen provides access to NAT, Firewall and IGMP Multicast settings. Enable each by selecting the appropriate checkbox . Click Next to continue or click Back to return to the previous step.
165 ENABLE NAT If the LAN is configured with a private IP address, the user should select this checkbox . The NAT submenu will appear in the Advanced Setup menu after reboot. On the other hand, if a private IP address is not used on the LAN side (i.e. the LAN side is using a public IP), this checkbox  should not be selected, so as to free up system resources for improved performance. ENABLE FULLCONE NAT This option becomes available when NAT is enabled. Known as one-to-one NAT, all requests from the same internal IP address and port are mapped to the same external IP address and port. An external host can send a packet to the internal host, by sending a packet to the mapped external address. ENABLE FIREWALL If this checkbox  is selected, the Security submenu will be displayed on the Advanced Setup menu after reboot. If firewall is not necessary, this checkbox  should not be selected so as to free up system resources for better performance. ENABLE IGMP MULTICAST Tick the checkbox  to enable Internet Group Membership Protocol (IGMP) multicast. IGMP is a protocol used by IPv4 hosts to report their multicast group memberships to any neighboring multicast routers. Enable WAN interface with base MAC Enable this option to use the router’s base MAC address as the MAC address for this WAN interface. STEP 4: To choose an interface to be the default gateway. Click Next to continue or click Back to return to the previous step.
166 STEP 5: Select DNS Server Interface from available WAN interfaces OR enter static DNS server IP addresses for the system. In ATM mode, if only a single PVC with IPoA or static IPoE protocol is configured, Static DNS server IP addresses must be entered. If IPv6 is enabled, an additional set of options will be shown. IPv6: Select the configured WAN interface for IPv6 DNS server information OR enter the static IPv6 DNS server Addresses.
167 Note that selecting a WAN interface for IPv6 DNS server will enable DHCPv6 Client on that interface. Click Next to continue or click Back to return to the previous step. STEP 6: The WAN Setup - Summary screen shows a preview of the WAN service you have configured. Check these settings and click Apply/Save if they are correct, or click Back to modify them. After clicking Apply/Save, the new service should appear on the main screen. To activate it you must reboot. Go to Management  Reboot and click Reboot.

170 E2.4 PPP over ATM (PPPoA) STEP 1: Click Next to continue. STEP 2: On the next screen, enter the PPP settings as provided by your ISP. Click Next to continue or click Back to return to the previous step.
171 PPP SETTINGS The PPP username and password are dependent on the requirements of the ISP. The user name can be a maximum of 256 characters and the password a maximum of 32 characters in length. (Authentication Method: AUTO, PAP, CHAP, or MSCHAP.)
172 KEEP ALIVE INTERVAL This option configures the interval between each PPP LCP request and the amount of time to wait for the PPP server to reply to the LCP request. If the time expired on all requests, the current PPP session would be dropped. ENABLE FULLCONE NAT This option becomes available when NAT is enabled. Known as one-to-one NAT, all requests from the same internal IP address and port are mapped to the same external IP address and port. An external host can send a packet to the internal host, by sending a packet to the mapped external address. DIAL ON DEMAND The NexusLink 3112u can be configured to disconnect if there is no activity for a period of time by selecting the Dial on demand checkbox . You must also enter an inactivity timeout period in the range of 1 to 4320 minutes. PPP IP EXTENSION The PPP IP Extension is a special feature deployed by some service providers. Unless your service provider specifically requires this setup, do not select it. PPP IP Extension does the following: • Allows only one PC on the LAN. • Disables NAT and Firewall. • The device becomes the default gateway and DNS server to the PC through DHCP using the LAN interface IP address. • The device extends the IP subnet at the remote service provider to the LAN PC. i.e. the PC becomes a host belonging to the same IP subnet. • The device bridges the IP packets between WAN and LAN ports, unless the packet is addressed to the device’s LAN IP address. • The public IP address assigned by the remote side using the PPP/IPCP protocol is actually not used on the WAN PPP interface. Instead, it is forwarded to the PC LAN interface through DHCP. Only one PC on the LAN can be connected to the remote, since the DHCP server within the device has only a single IP address to assign to a LAN device. ENABLE NAT If the LAN is configured with a private IP address, the user should select this checkbox . The NAT submenu will appear in the Advanced Setup menu after reboot. On the other hand, if a private IP address is not used on the LAN side (i.e. the LAN side is using a public IP), this checkbox  should not be selected to free up system resources for better performance. ENABLE FIREWALL If this checkbox  is selected, the Security submenu will be displayed on the Advanced Setup menu after reboot. If firewall is not necessary, this checkbox  should not be selected to free up system resources for better performance.
173 USE STATIC IPv4 ADDRESS Unless your service provider specially requires it, do not select this checkbox . If selected, enter the static IP address in the IP Address field. Also, don’t forget to adjust the IP configuration to Static IP Mode as described in section 3.2. Fixed MTU Fixed Maximum Transmission Unit. The size (in bytes) of largest protocol data unit which the layer can pass onwards. This value is 1500 for PPPoA. ENABLE PPP DEBUG MODE When this option is selected, the system will put more PPP connection information into the system log. This is for debugging errors and not for normal usage. ENABLE IGMP MULTICAST PROXY Tick the checkbox  to enable Internet Group Membership Protocol (IGMP) multicast. This protocol is used by IPv4 hosts to report their multicast group memberships to any neighboring multicast routers.
