– 54 –5WLAN CONFIGURATIONThis chapter describes wireless configuration on the ADSL Router. The unit contains an onboard IEEE 802.11b/g/n access point (AP), which provides wireless data communications between the router and wireless devices.WLAN Configuration contains the following sections:◆“WLAN Basic Settings” on page 55◆“Advanced Settings” on page 57◆“Wireless Security Setup” on page 59◆“Access Control” on page 64◆“Wi-Fi Protected Setup (WPS)” on page 65◆“MBSSID” on page 66◆“WDS” on page 68

CHAPTER 5 | WLAN ConfigurationWLAN Basic Settings– 55 –WLAN BASIC SETTINGSThe unit’s access point can function in one of three modes, mixed 802.11b/g, 802.11b only, or 802.11g only. Also note that 802.11g is backward compatible with 802.11b at slower data rates.Note that the unit supports two virtual access point (VAP) interfaces.Figure 20: WLAN Basic SettingsThe following items are displayed on this page:◆Disable Wireless LAN Interface — Disables the Wireless LAN interface. (Default: Enabled)◆Band — Defines the radio mode. (Default: 2.4Ghz (B+G))◆Mode — The unit can function as an access point alone, allowing connection to wireless clients, or both access point and WDS (wireless distribution system), allowing WDS transparent bridging between APs. (Default: AP+WDS)◆SSID — The service set identifyer for the access point. (Default: SMC)◆Channel Width — The router provides a channel bandwidth of 40 MHz by default giving an 802.11g connection speed of 108 Mbps (sometimes referred to as Turbo Mode) and a 802.11n connection speed of up to 150 Mbps. Setting the HT Channel Bandwidth to 20 MHz slows connection speed for 802.11g and 802.11n to 54 Mbps and 74

CHAPTER 5 | WLAN ConfigurationWLAN Basic Settings– 56 –Mbps respectively and ensures backward compliance for slower 802.11b devices. (Default: 40MHz)◆Control Sideband — Specifies if the extension channel should be in the Upper or Lower sideband. When a 40MHz channel bandwidth has been set, the extension channel option will be enabled in the upper or lower sideband. The extension channel allows you to get extra bandwidth. ◆Channel Number — The radio channel that the ADSL Router uses to communicate with wireless clients. When multiple access points are deployed in the same area, set the channel on neighboring access points at least five channels apart to avoid interference with each other. For example, you can deploy up to three access points in the same area using channels 1, 6, 11. Note that wireless clients automatically set the channel to the same as that used by the ADSL Router to which it is linked. (Default: Auto; Range: 1~11)◆Radio Power (percent) — Adjusts the power of the radio signals transmitted from the access point. The higher the transmission power, the farther the transmission range. Power selection is not just a trade off between coverage area and maximum supported clients. You also have to ensure that high-power signals do not interfere with the operation of other radio devices in the service area. (Default: 100%; Range: 100%, 80%, 50%, 25%, 10%)◆Associated Clients — Opens a window that displays information on current connected wireless clients.

CHAPTER 5 | WLAN ConfigurationAdvanced Settings– 57 –ADVANCED SETTINGSThe advanced radio configuration settings are described in the page that follows.Figure 21: Wireless Security Setup - Advanced SettingsThe following items are displayed on this page:◆Authentication Type — Sets the basic authentication method.◆Fragment Threshold — Configures the minimum packet size that can be fragmented when passing through the wireless interface. Fragmentation of the PDUs (Package Data Unit) can increase the reliability of transmissions because it increases the probability of a successful transmission due to smaller frame size. If there is significant interference present, or collisions due to high network utilization, try setting the fragment size to send smaller fragments. This will speed up the retransmission of smaller frames. However, it is more efficient to set the fragment size larger if very little or no interference is present because it requires overhead to send multiple frames. (Range: 256-2346 bytes; Default: 2346 bytes)◆RTS Threshold — Sets the packet size threshold at which a Request to Send (RTS) signal must be sent to a receiving station prior to the sending station starting communications. The wireless interface sends RTS frames to a receiving station to negotiate the sending of a data frame. After receiving an RTS frame, the station sends a CTS (clear to send) frame to notify the sending station that it can start sending data.◆Beacon Interval — The rate at which beacon signals are transmitted from the wireless interface. The beacon signals allow wireless clients to

CHAPTER 5 | WLAN ConfigurationAdvanced Settings– 58 –maintain contact with the ADSL Router. They may also carry power-management information. (Range: 20-1000 TUs; Default: 100 TUs)◆DTIM Interval — The rate at which stations in sleep mode must wake up to receive broadcast/multicast transmissions. Known also as the Delivery Traffic Indication Map (DTIM) interval, it indicates how often the MAC layer forwards broadcast/multicast traffic, which is necessary to wake up stations that are using Power Save mode. The default value of one beacon indicates that the access point will save all broadcast/multicast frames for the Basic Service Set (BSS) and forward them after every beacon. Using smaller DTIM intervals delivers broadcast/multicast frames in a more timely manner, causing stations in Power Save mode to wake up more often and drain power faster. Using higher DTIM values reduces the power used by stations in Power Save mode, but delays the transmission of broadcast/multicast frames. (Range: 1-255 beacons; Default: 1 beacon)◆Data Rate — The maximum data rate at which the wireless interface transmits multicast and broadcast packets. (Options: Auto, 1, 2, 5.5, 11, 6, 9, 18, 24, 36, 48, 54 Mbps; Default: Auto)◆Preamble Type — Sets the length of the signal preamble that is used at the start of a data transmission. (Default: Long)■Long Preamble: Sets the preamble to long (192 microseconds). Using a long preamble ensures the wireless interface can support all 802.11b and 802.11g clients.■Short Preamble: Sets the preamble according to the capability of clients that are currently asscociated. Uses a short preamble (96 microseconds) if all associated clients can support it, otherwise a long preamble is used. The wireless interface can increase data throughput when using a short preamble, but will only use a short preamble if it determines that all associated clients support it.◆Broadcast SSID — Enables/disables the wireless interface to broadcast an SSID (service set identifier) to uniquely identify it on the network.◆Aggregation — This option enables Mac Service Data Unit (MSDU) aggregation. (Default: Enabled)◆Short GI — The guard interval between symbols helps receivers overcome the effects of multipath delays. You can enable a short interval to increase throughput. (Default: Enabled)

(Options: Root, VAP0-VAP3)◆Encryption — Selects the encryption type to deploy on the specified VAP. The options are:■None: No security.■WEP: WEP is used as the multicast encryption cipher. You should select WEP only when both WPA and WEP clients are supported.■WPA(TKIP/AES): WPA employs a combination of several technologies to provide an enhanced security solution for 802.11 wireless networks. TKIP or AES is used as the multicast encryption cipher.■WPA2(TKIP/AES): WPA2 – WPA was introduced as an interim solution for the vulnerability of WEP pending the ratification of the IEEE 802.11i wireless security standard. In effect, the WPA security features are a subset of the 802.11i standard. WPA2 includes the now ratified 802.11i standard, but also offers backward compatibility with WPA. Therefore, WPA2 includes the same 802.1X

CHAPTER 5 | WLAN ConfigurationWi-Fi Protected Setup (WPS)– 65 –WI-FI PROTECTED SETUP (WPS)Wi-Fi Protected Setup (WPS) is designed to ease installation and activation of security features in wireless networks. WPS has two basic modes of operation, Push-button Configuration (PBC) and Personal Identification Number (PIN). The WPS PIN setup is optional to the PBC setup and provides more security. The WPS button on the router can be pressed at any time to allow a single device to easily join the network.The WPS Settings page includes configuration options for setting WPS device PIN codes and activating the virtual WPS button.Figure 28: WPS ConfigurationThe following items are displayed on this page:◆Disable WPS — Disables WPS configuration. (Default: Disabled)◆WPS Status — Displays if there is currently any WPS traffic connecting to the router. ◆Self PIN Number — Displays the PIN Code for the router. The default is exclusive for each unit.◆Regenerate PIN — Click the button to generate a new PIN number that is used by the router.◆Push Button Configuration — The “Start PBC” button has the same effect as pressing the physical WPS button that is located on the rear of the router. After clicking on the button you have up to two minutes to activate WPS on a device that needs to join the network.◆Apply Changes — Applies the current WPS settings.

CHAPTER 5 | WLAN ConfigurationMBSSID– 66 –◆Reset — Resets the WPS settings to factory default values.◆Client PIN Number — Enters a PIN number of a wireless client device that needs to join the network. Click “Start PIN” to activate the WPS process.MBSSIDThis page configures up to four VAPs (virtual access points) on the ADSL Router. Each VAP functions as a separate access point, and can be configured with its own Service Set Identification (SSID) and security settings. However, most radio signal parameters apply to both VAP interfaces.The VAPs function similar to a VLAN, with each VAP mapped to its own VLAN ID. Traffic to specific VAPs can be segregated based on user groups or application traffic. Each VAP can have its own wireless clients, whereby the clients associate with these VAPs the same as they would with a physical access point.

CHAPTER 5 | WLAN ConfigurationMBSSID– 67 –Figure 29: Second BSSIDThe following items are displayed on this page:◆Enable (VAP0-VAP3) — Enables up to four VAP interfaces on the router. (Default: Disabled)◆SSID — Configures the service set identifier of a VAP on the wireless interface.

To set up bridge links between access point units, you must configure the wireless Distribution System (WDS) forwarding table by specifying the wireless MAC address of all units to which you want to forward traffic. Up to six WDS bridge links can be specified for each unit in the wireless bridge network.Figure 30: WDS ConfigurationTo set up WDS all connected routers should be in the same subnet, with DHCP disabled on all routers not connected to the WAN and the MAC address of each router set first.Follow the steps detailed below:1. The wireless setup must be the same on all connected routers.

You can use the web browser interface to access IP addressing only if the ADSL Router already has an IP address that is reachable through your network. ◆“LAN Interface” on page 73◆“IPv6 LAN Configuration” on page 74◆“DHCP Settings” on page 76

CHAPTER 6 | LAN SettingsLAN Interface– 73 –LAN INTERFACEBy default, the ADSL Router is configured with the IP address 192.168.2.1, subnet mask 255.255.255.0 and a default gateway of 192.168.2.1. Figure 34: LAN ConfigurationThe following items are displayed on this page:◆Interface Name — Displays the name assigned to the interface.◆IP Address — Specifies an IP address for management of the ADSL Router. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods. (Default: 192.168.2.1.)◆Subnet Mask — Indicates the local subnet mask. (Default: 255.255.255.0)◆Secondary IP Address — Specifies a secondary IP address for management of the unit.◆IGMP Snooping — Enables Internet Group Management Protocol (IGMP) multicast filtering.

For devices that need Internet access through the LAN port, enter the MAC address and click Add.IPV6 LAN CONFIGURATIONThis section describes how to configure an initial IPv6 interface for management access over the network, or for creating an interface to multiple subnets. This router supports both IPv4 and IPv6, and can be managed through either of these address types.IPv6 includes two distinct address types – link-local unicast and global unicast. A link-local address makes the router accessible over IPv6 for all devices attached to the same local subnet. However, to connect to a larger network with multiple segments, the router must be configured with a global unicast address.Figure 35: IPv6 LAN Configuration

CHAPTER 6 | LAN SettingsIPv6 LAN Configuration– 75 –The following items are displayed on this page:RA SETTING◆Enable — Enables IPv6 router advertisements on the router.◆M Flag — Sets the router advertisement “Managed address configuration" flag. When set, the router will use DHCPv6 to obtain stateful addresses.◆O Flag — Sets the router advertisement “other stateful configuration” flag. When set, the router will attempt to acquire other non-address configuration information (such as a default gateway or DNS).◆Max Interval — The amount of time that a remote IPv6 node is considered reachable.◆Min Interval — The interval between transmitting IPv6 neighbor solicitation messages.◆Prefix Mode — Enables manual or automatic configuration of IPv6 addresses on the router. ■Auto — Enables automatic configuration of IPv6 addresses on interfaces and enables IPv6 functionality on the router.

DHCP DISABLED By selecting “None,” you can disable DHCP on the ADSL Router.Figure 36: DHCP DisabledThe following items are displayed on this page:◆DHCP Mode — When set to “None,” disables DHCP on the unit.

CHAPTER 6 | LAN SettingsDHCP Settings– 77 –DHCP RELAY Dynamic Host Configuration Protocol (DHCP) can dynamically allocate an IP address and other configuration information to network clients that broadcast a request. To receive the broadcast request, the DHCP server would normally have to be on the same subnet as the client. However, when the access point’s DHCP relay agent is enabled, received client requests can be forwarded directly by the access point to a known DHCP server on another subnet. Responses from the DHCP server are returned to the access point, which then broadcasts them back to clients.Figure 37: DHCP RelayThe following items are displayed on this page:◆DHCP Mode — When set to “DHCP Relay,” enables routing of the DHCP service to units on a different subnet.◆Relay Server — Enter the address of the DHCP server for routing to other units.

CHAPTER 6 | LAN SettingsDHCP Settings– 78 –DHCP SERVER The unit can support up to 253 local clients. Addresses are assigned to clients from a common address pool configured on the unit. Configure an address pool by specifying start and end IP addresses. Be sure not to include the unit's IP address in the address pool range.Figure 38: DHCP ServerThe following items are displayed on this page:◆LAN IP Address — Displays the LAN IP address for management of the ADSL Router. (Default: 192.168.2.1.)◆Subnet Mask — Displays the local subnet mask.

– 81 –7WAN SETTINGSThis chapter describes WAN configuration on the ADSL Router. The WAN pages are used to configure standard WAN services, including VPI, VCI, encapsulation, service type (PPPoE, IPoE, bridging), ATM settings and ADSL settings. It includes the following sections:◆“Channel Configuration” on page 82◆“ATM Settings” on page 84◆“ADSL Settings” on page 86

CHAPTER 7 | WAN SettingsChannel Configuration– 82 –CHANNEL CONFIGURATIONThe Channel Configuration page configures channel operation modes of the ADSL Router. Figure 41: WAN ConfigurationThe following items are displayed on this page:◆Default Route Selection – Enables the default route to be specified or selected automatically.◆VPI (Virtual Path Identifier) – A grouping of virtual channels which connect the same end-points, and which share a traffic allocation. ◆VCI (Virtual Channel Identifier) – A specific virtual channel connecting two end-points.◆Encapsulation:■LLC (Logical Link Control) – This encapsulation method allows multiplexing of multiple protocols over a single ATM virtual connection. In some cases, the LLC header is followed by a SNAP header which uniquely identifies a routed or bridged protocol. (This is the default packet encapsulation format used for carrying IP datagrams over AAL5 ATM.)

CHAPTER 7 | WAN SettingsChannel Configuration– 83 –■VC/MUX (Virtual Circuit Multiplexing) – When using this mode, the communicating hosts agree on the high-level protocol for a given circuit, which tends to reduce fragmentation overhead. This allows a sender to pass each datagram directly to AAL5 for transfer, and requires nothing to be sent besides the datagram and the AAL5 trailer. The chief disadvantage of this scheme is that a host must create a separate virtual circuit for each high-level protocol if more than one protocol is used. Because most carriers charge for each virtual circuit, customers try to avoid using multiple circuits because it adds unnecessary cost.◆Channel Mode — The protocol used on the channel, as specified by the service provider. Choose from the following options:■1483 Bridged — The Bridged RFC 1483 Encapsulated Traffic over ATM feature allows you to send bridged RFC 1483 encapsulated packets over ATM switched virtual circuits (SVCs). ■1483 MER — 1483 MER is an RFC standard MAC Encapsulated Routing protocol. ■PPPoE — Point-to-Point Protocol over Ethernet (PPPoE).■PPPoA — Point-to-Point Protocol over Asynchronous Transfer Mode (PPPoA).■1483 Routed — Allows you to send routed RFC 1483 encapsulated packets over ATM switched virtual circuits (SVCs). ■IPoA — Dynamic IP over ATM (IPoA).◆Enabled NAPT — Enables Network Address Port Translation for the channel.◆Enable IGMP — Enables IGMP for the channel.◆PPP Settings — Configures settings for PPPoE and PPPoA modes.■User Name — The PPP access user name provided by the ISP.■Password — The PPP access password provided by the ISP.■Type — Selects the connection type; Continuous, Connect on Demand, or Manual.■Idle Time — The number of minutes you want to have elapsed before your Internet access disconnects in Connect-on-Demand mode.◆WAN IP Settings — Configures settings for 1483 MER, 1483 Routed, and IPoA modes.■Type — Selects fixed IP or DHCP. When fixed IP is selected, enter the local IP address, gateway, and subnet mask. When DHCP is

CHAPTER 7 | WAN SettingsATM Settings– 84 –selected, the WAN interface IP address is assigned by the remote DHCP server.■Local IP address — The IP address of the WAN interface provided by the ISP.■Gateway — The IP address of the remote gateway router provided by the ISP.■Netmask — The subnet mask for the local IP address.■Default Route — Enables or disables the default route IP address.■Unnmbered — Enables the IP unnumbered feature.ATM SETTINGSThe ATM Settings page is used to configure the settings between your ADSL Router and the remote ATM PVC switch, including connection mode (single or multiple service over one connection), and packet level QoS. The ATM Settings parameters form a Traffic Contract that informs the network what type of traffic is to be transported and the performance requirements of the traffic.Figure 42: ATM SettingsThe following items are displayed on this page:◆Select — Clicking the radio button associated with the connection makes the parameters editable.◆VPI (Virtual Path Identifier) — Adds a VPI entry to the table. (Range: 0-255; Default: 0)

(Range: 32-65535; Default: 35)◆QoS — Selects packet level Quality of Service (QoS) for the connection. Options are:■UBR (Unspecified Bitrate): Configures a PVC with a Peak Cell Rate indicating the maximum number of ATM cells that can be sent in a burst.■CBR (Constant Bitrate): Configures a PVC at a constant bit rate. This option may be required for connections that depend on precise clocking to ensure undistorted delivery.■nrt-VBR (non-realtime Variable Bitrate): Configures a PVC at a non-realtime variable bit rate. This option may be used for applications not sensitive to changes in available bandwidth, such as data.■rt-VBR (realtime Variable Bitrate): Configures a PVC at a real-time variable bit rate. This option may be used for applications that have a lot of variance in required bandwidth, such as voice.◆PCR (Peak Cell Rate) — Configures the maximum allowable rate at which cells can be transported along a connection in the ATM network. The PCR is the determining factor in how often cells are sent in relation to time in an effort to minimize jitter.◆CDVT (Cell Delay Variation Tolerance) — Configures the maximum amount of jitter permissable.◆SCR (Sustainable Cell Rate) — Configures the average allowable, long-term cell transfer rate on a specific connection.◆MBS (Maximum Burst Size) — Configures the maximum allowable burst size of cells that can be transmitted contiguously on a particular connection.◆Current ATM VC Table — The Current ATM VC Table lists the current ATM settings configured on your ADSL Router. By selecting the connection using the radio button associated with it you can edit the connection parameters.

CHAPTER 7 | WAN SettingsADSL Settings– 86 –ADSL SETTINGSThe ADSL Settings page configures the ADSL modulation type, ADSL2+ related parameters, capabilities and the ADSL tone mask.Figure 43: ATM SettingsThe following items can be enabled on this page:◆ADSL Modulation — ADSL Modulation refers to a frequency-division multiplexing (FDM) scheme utilized as a digital multi-carrier modulation method for DSL. A large number of closely-spaced orthogonal sub-carriers are used to carry data. The data is divided into several parallel data streams or channels, one for each sub-carrier. Each sub-carrier is modulated with a conventional modulation scheme (such as G.lite, ADSL2, etc. or more commonly ADSL2+).■G.lite — A standard that defines the more economical splitterless ADSL connection that transmits data at up to 1.5 Mbps downstream and 512 Kbps upstream. This ADSL option can be installed without an on-site visit by the service provider.■G.dmt — A standard that defines full-rate ADSL, and utilizes Discrete Multi-Tone (DMT) signaling to transmit data at up to 8 Mbps downstream and 640 Kbps upstream.■T1.413 — ANSI standard that defines the requirements for ADSL for the interface between the telecommunications network and the customer installation in terms of their interaction and electrical characteristics. (The Gateway complies with Issue 2 of this standard.)

CHAPTER 7 | WAN SettingsADSL Settings– 87 –■ADSL2 — This standard extends the capability of basic ADSL data rates to 12 Mbit/s downstream and 3 Mbit/s upstream (with a mandatory capability of ADSL2 transceivers of 8 Mbit/s downstream and 800 Kbit/s upstream.■ADSL2+ — This standard extends the capability of basic ADSL data rates to 24 Mbit/s downstream and 1.4 Mbit/s upstream depending on the distance from the DSLAM to the customer's home.◆AnnexL Option — Annex L is an optional specification in the ITU-T ADSL2 recomendation G.992.3 titled “Specific requirements for a Reach Extended ADSL2 (READSL2) system operating in the frequency band above POTS.” It is often referred to as Reach Extended ADSL2 or READSL2. Once enabled AnnexL increases the range of DSL service, enabling the link to work at a distance of 7 kilometers, or 23,000 feet.◆AnnexM Option — Annex M is an optional specification in ITU-T recomendations G.992.3 (ADSL2) and G.992.5 (ADSL2+), also referred to as ADSL2 M and ADSL2+ M. This specification extends the capability of commonly deployed Annex A by more than doubling the number of upstream bits.Once enabled AnnexM increases upload speeds by the shifting the upstream/downstream frequency split from 138 kHz up to 276 kHz, allowing the maximum upstream bandwidth to be increased from 1.4 Mbit/s to 3.3 Mbit/s.◆ADSL Capability — ADSL Capability refers to means of manipulating the bit loading of a connection to increase quality of signal or transmission rate.■Bitswap — Enables bit swapping. Bit swapping is a way of swapping the bit-loading of a noisy tone with another tone in the symbol which is not as noisy. The bit loading from a specific tone can be increased or decreased. In addition, the TX power can be increased or decreased for a specific tone. However, there is no change in the overall payload rate after the bit swap operation.■SRA — Enables seamless rate adaptation to set the optimal transmission rate based on existing line conditions.

CHAPTER 8 | ServicesNAT/NAPT Settings– 97 –NAT/NAPT SETTINGSNetwork Address Translation (NAT) is a standard method of mapping multiple “internal” IP addresses to one “external” IP address on devices at the edge of a network. For the router, the internal (local) IP addresses are the IP addresses assigned to local PCs by the DHCP server, and the external IP address is the IP address assigned to the specified WAN interface. The NAT function on the router enables the support of Virtual Servers, Port Triggering, and other features. Some applications, such as Internet gaming, videoconferencing, Internet telephony and others, require multiple connections. These applications may not work with Network Address Translation (NAT) enabled. If you need to run applications that require multiple connections, use Port Triggering to specify the additional public ports to be opened for each application. Alternatively, you can open up a client to unrestricted two-way Internet access by defining it as DMZ (demilitarized-zone) host.VIRTUAL SERVERS Using the NAT Virtual Server feature, remote users can access different servers on your local network using your single public IP address.Remote users accessing services such as web or FTP at your local site thorugh your public IP address, are redirected (mapped) to other local server IP addresses and TCP/UDP port numbers. For example, if you set Type/Public Port to TCP/80 (HTTP or web) and the Private IP/Port to 192.168.7.9/80, then all HTTP requests from outside users forwarded to 192.168.7.9 on port 80. Therefore, by just using your external IP address provided by your ISP, Internet users can access the services they need at the local addresses to which you redirect them.The more common TCP service port numbers include: HTTP: 80, FTP: 21, Telnet: 23, and POP3: 110. Up to 32 entries can be configured in the Virtual Servers table.

Some Internet applications, such as interactive games or videoconferencing, may not function properly behind the router's firewall. By specifying a Demilitarized Zone (DMZ) host, the PC's TCP ports are completely exposed to the Internet, allowing open two-way communication. The host PC should be assigned a static IP address.Figure 59: DMZ SettingsThe following items are displayed on this page:◆Enable DMZ — Sets the DMZ status to enabled, but changes do not take affect until the Apply changes button has been pressed and changes are saved to the running configuration.

CHAPTER 8 | ServicesDoS– 109 –DOSDenial of Service (DoS) is an attempt by a hacker to flood an IP address, domain, or server with repeated external communincation requests, effectively saturating the system with an information flood that renders it slow or effectively inoperable for genuine users to access it. DoS attacks are also referred to as non-intrusion attacks, the goal of which is to cripple your system but not steal data. The DoS Settings on the router enable the user to block many of the common DoS attacks a network might suffer.Figure 62: DoS SettingsThe following items are displayed on this page:◆Enable DoS Blocking — Activates the DoS check boxes and configurable parameters associated with them. (Default: Disabled)■Whole System Flood: SYN: Prevents a SYN (synchronise) attack in which the process of the common three way TCP handshake is interupted and the acknowledge response gets sent to a maicious IP address, or the system is flooded with false SYN requests.

The fragmented packets are processed by the unit causing it to crash.■PingofDeath: Prevents the receival of an oversized ping packet that the unit cannot handle. Normal ping packets are 56 bytes, or 84 bytes with the IP header attached. The Ping of Death will exceed the maximum IP packet size of 65,535 bytes.■TCP Scan: Prevents the probing of the unit by a hacker for open TCP ports to then block.

CHAPTER 8 | ServicesIGMP Proxy Configuration– 111 –■TCP SynWithData: Prevents the hacker sending a volume of requests for connections that cannot be completed.■UDP Bomb: Also called a UDP Flood or packet storm. Prevents the hacker congesting the network by generating a flood of UDP packets between it and the unit using the UDP chargen service (a testing utility that generates a character string for every packet it receives).■UDP EchoChargen: Prevents the hacker from sending a UDP packet to the echo server with a source port set to the chargen port. ■packets/second: Enter the number of packets per second that you want to scan for malicious activity.■Sensitivity: Specifies the sensivity of the TCP/UDP port scan prevention.

Using multicasting as opposed to sending the same data to the individual hosts uses less network bandwidth. The multicast feature also enables you to receive multicast video stream from multicast servers.IP hosts use Internet Group Management Protocol (IGMP) to report their multicast group memberships to neighboring routers. Similarly, multicast routers use IGMP to discover which of their hosts belong to multicast groups. This device supports IGMP proxy that handles IGMP messages. When enabled, this device acts as a proxy for a LAN host making requests to join and leave multicast groups, or a multicast router sending multicast packets to multicast group on the WAN side. When you enable IGMP Proxy, make sure IGMP is also enabled on the WAN interface (upstream) that connects to a router running IGMP. You must also enable IGMP on the LAN interface (downstream) that is connected to hosts.

CHAPTER 8 | ServicesIGMP Proxy Configuration– 112 –Figure 63: IGMP Proxy ConfigurationThe following items are displayed on this pages:◆IGMP Proxy — Enables IGMP proxy. When enabled, the upstream interface acts as a host interface, sending query messages periodically to the downstream interfaces, sending join and leave messages to the upstream multicast router when a first join or last leave message is received from a downstream interface, and sending membership reports in response to query messages from the multicast router.◆Multicast Allowed — Enables multicast forwarding. (Default: Enabled)◆Robustness Count — Specifies the robustness (or expected packet loss) for interfaces. The robustness value is used in calculating the appropriate range for other IGMP variables. (Range: 1-255; Default: 2)◆Last Member Query Count — The number of query messages sent before the router determines that there are no remaining members of the specific host group being queried on the interface. (Range: 1-255; Default: 2)◆Query Interval — The interval between sending IGMP general queries. (Range: 2-31744 seconds; Default: 60 seconds)◆Query Response Interval — The maximum time the system waits for a response to general queries. (Range: 10-31744 tenths of a second; Default: 10 seconds)◆Group Leave Delay — The time duration it takes a device to stop forwarding multicast frames after an IGMP Leave Group message has been successfully sent to the device. (Default: 2000 ms)

CHAPTER 8 | ServicesRIP Configuration– 113 –RIP CONFIGURATIONRIP is an Internet protocol you can set up to share routing table information with other routing devices on your LAN, at your ISP’s location, or on remote networks connected to your network via the ADSL line. Most small home or office networks do not need to use RIP; they have only one router, such as the router, and one path to an ISP. In these cases, there is no need to share routes, because all Internet data from the network is sent to the same ISP gateway. Figure 64: RIP ConfigurationThe following items are displayed on this pages:◆RIP — Enables or disables RIP on the unit. (Default: Disabled)◆Interface — The name of the interface on which you want to enable RIP. (Default: br0)◆Receive Version — Indicate the RIP version in which information must be passed to the DSL device in order for it to be accepted into its routing table. ◆Send Version — Indicate the RIP version this interface will use when it sends its route information to other devices.

CHAPTER 8 | ServicesARP Binding Configuration– 114 –ARP BINDING CONFIGURATIONThe router uses its tables to make routing decisions, and uses Address Resolution Protocol (ARP) to forward traffic from one hop to the next. ARP is used to map an IP address to a physical layer MAC address. When an IP frame is received by the router, it first looks up the MAC address corresponding to the destination IP address in the ARP cache. If the address is found, the router writes the MAC address into the appropriate field in the frame header, and forwards the frame on to the next hop. IP traffic passes along the path to its final destination in this way, with each routing device mapping the destination IP address to the MAC address of the next hop toward the recipient, until the packet is delivered to its final destination.For devices that do not respond to ARP requests or do not respond in a timely manner, traffic will be dropped because the IP address cannot be mapped to a MAC address. If this occurs, you can use ARP Binding to manually map an IP address to the corresponding MAC address in the ARP cache.Figure 65: ARP Binding ConfigurationThe following items are displayed on this pages:◆IP Address – IP address statically mapped to a physical MAC address. (Valid IP addresses consist of four numbers, 0 to 255, separated by periods, and must match a known network interface)◆MAC Address – MAC address statically mapped to the corresponding IP address. (Valid MAC addresses are hexadecimal numbers in the format: xxxxxxxxxxxx)

Each packet contains information about its origin and destination. When a packet is received, a network device examines the packet and matches it to the routing table entry providing the best match for its destination. The table then provides the device with instructions for sending the packet to the next hop on its route across the network.Figure 68: Routing ConfigurationThe following items are displayed on this page:◆Enable — Enables static routing on the ADSL Router. (Default: Enabled)◆Destination — The network IP address of the subnet. The destination can be specified as the IP address of a subnet or a specific host in the subnet.

CHAPTER 10 | DiagnosticsTraceroute– 128 –TRACEROUTETraceroute discovers the routes that packets take when traveling to a destination. Traceroute works by taking advantage of the error messages generated by routers when a packet exceeds its time-to-live (TTL) value.The traceroute command first sends probe datagrams with the TTL value set at one. This causes the first router to discard the datagram and return an error message. The trace function then sends several probe messages at each subsequent TTL level and displays the roundtrip time for each message. Not all devices respond correctly to probes by returning an “ICMP port unreachable” message. If the timer goes off before a response is returned, the trace function prints a series of asterisks and the “Request Timed Out” message. A long sequence of these messages, terminating only when the maximum timeout has been reached, may indicate this problem with the target device. A trace terminates when the destination responds, when the maximum timeout (TTL) is exceeded, or the maximum number of hops is exceeded.Figure 78: TracerouteThe following items are displayed on this page:◆Host — The IP address of the destination host.◆Number of Tries — The number of datagrams to be sent at each TTL level. The default count is 3. (Range: 1–10)◆Timeout — The number of seconds to wait for a response to a probe packet. The default is 5000 ms. (Range: 1–65535)◆Datasize — Number of bytes in the packet. The default is 38 bytes. (Range: 64-1518)◆DSCP — The DSCP value in the IP Header of the packet. (Range: 0-63)◆Max Hop Count — The largest TTL value that can be used.

– 147 –CCABLES AND PINOUTSTWISTED-PAIR CABLE ASSIGNMENTSFor 10/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable. NOTE: Each wire pair must be attached to the RJ-45 connectors in a specific orientation.CAUTION: DO NOT plug a phone jack connector into the RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.The following figure illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins.Figure 87: RJ-45 Connector1881

APPENDIX C | Cables and Pinouts10/100BASE-TX Pin Assignments– 148 –10/100BASE-TX PIN ASSIGNMENTSUse unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).The RJ-45 port on the router supports automatic MDI/MDI-X operation, so you can use straight-through or crossover cables for all network connections to PCs, switches, or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the cable. STRAIGHT-THROUGH WIRINGIf the twisted-pair cable is to join two ports and only one of the ports has an internal crossover (MDI-X), the two pairs of wires must be straight-through. (When auto-negotiation is enabled for any RJ-45 port on this gateway, you can use either straight-through or crossover cable to connect to any device type.)Figure 88: Straight-through WiringTable 5: 10/100BASE-TX MDI and MDI-X Port PinoutsPIN MDI Signal Nameaa.
