84 Field Description 802.11n/EWC An equipment interoperability standard setting based on IEEE 802.11n Draft 2.0 and Enhanced Wireless Consortium (EWC) Bandwidth Select 20GHz or 40GHz bandwidth. 40GHz bandwidth uses two adjacent 20GHz bands for increased data throughput. Control Sideband Select Upper or Lower sideband when in 40GHz mode. 802.11n Rate Set the physical transmission rate (PHY). 802.11n Protection Turn Off for maximized throughput. Turn On for greater security. RIFS Advertisement Reduced Interframe Space is the creation of a short time delay between PDUs to improve wireless efficiency. OBSS Co-Existence Co-existence between 20 MHZ AND 40 MHZ overlapping Basic Service Set (OBSS) in WLAN. RX Chain Power Save Enabling this feature turns off one of the Receive chains, going from 2x2 to 2x1 to save power. RX Chain Power Save Quiet Time The number of seconds the traffic must be below the PPS value below before the Rx Chain Power Save feature activates itself. RX Chain Power Save PPS The maximum number of packets per seconds that can be processed by the WLAN interface for a duration of Quiet Time, described above, before the Rx Chain Power Save feature activates itself. Support 802.11n Client Only Turn Off to allow 802.11b/g clients access to the router. Turn On to prohibit 802.11b/g clients access to the router. 54g Rate Drop-down menu that specifies the following fixed rates: Auto: Default. Uses the 11 Mbps data rate when possible but drops to lower rates when necessary. 1 Mbps, 2Mbps, 5.5Mbps, or 11Mbps fixed rates. The appropriate setting is dependent on signal strength. Multicast Rate Setting for multicast packet transmit rate (1-54 Mbps) Basic Rate Setting for basic transmission rate. Fragmentation Threshold A threshold, specified in bytes, that determines whether packets will be fragmented and at what size. On an 802.11 WLAN, packets that exceed the fragmentation threshold are fragmented, i.e., split into, smaller units suitable for the circuit size. Packets smaller than the specified fragmentation threshold value are not fragmented. Enter a value between 256 and 2346. If you experience a high packet error rate, try to slightly increase your Fragmentation Threshold. The value should remain at its default setting of 2346. Setting the Fragmentation Threshold too low may result in poor performance. RTS Threshold Request to Send, when set in bytes, specifies the packet size beyond which the WLAN Card invokes its RTS/CTS mechanism. Packets that exceed the specified RTS threshold trigger the RTS/CTS mechanism. The NIC transmits smaller packet without using RTS/CTS. The default setting of 2347 (maximum length) disables RTS Threshold. PDF created with pdfFactory Pro trial version www.pdffactory.com
85 Field Description DTIM Interval Delivery Traffic Indication Message (DTIM) is also known as Beacon Rate. The entry range is a value between 1 and 65535. A DTIM is a countdown variable that informs clients of the next window for listening to broadcast and multicast messages. When the AP has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. AP Clients hear the beacons and awaken to receive the broadcast and multicast messages. The default is 1. Beacon Interval The amount of time between beacon transmissions in milliseconds. The default is 100 ms and the acceptable range is 1 – 65535. The beacon transmissions identify the presence of an access point. By default, network devices passively scan all RF channels listening for beacons coming from access points. Before a station enters power save mode, the station needs the beacon interval to know when to wake up to receive the beacon (and learn whether there are buffered frames at the access point). Global Max Clients The maximum number of clients that can connect to the router. Xpress TM Technology Xpress Technology is compliant with draft specifications of two planned wireless industry standards. Transmit Power Set the power output (by percentage) as desired. WMM (Wi-Fi Multimedia) The technology maintains the priority of audio, video and voice applications in a Wi-Fi network. It allows multimedia service get higher priority. WMM No Acknowledgement Refers to the acknowledge policy used at the MAC level. Enabling no Acknowledgement can result in more efficient throughput but higher error rates in a noisy Radio Frequency (RF) environment. WMM APSD This is Automatic Power Save Delivery. It saves power.

97 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 à Security à 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. PDF created with pdfFactory Pro trial version www.pdffactory.com
98 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 à Security à 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. PDF created with pdfFactory Pro trial version www.pdffactory.com
99 DAYTIME PARENTAL CONTROL This feature restricts access of a selected LAN device to an outside Network through the NEXUSLINK 3111u, 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. PDF created with pdfFactory Pro trial version www.pdffactory.com

114 Appendix G - Connection Setup Creating a WAN connection is a two-stage process. 1 - Setup a Layer 2 Interface (ATM, PTM or Ethernet). 2 - Add a WAN connection to the Layer 2 Interface. The following sections describe each stage in turn. G1 ~ Layer 2 Interfaces Every layer2 interface operates in one of three modes: Default, VLAN Mux or MSC. A short introduction to each of these three modes is included below for reference. It is important to understand the differences between these connection modes, as they determine the number and types of connections that may be configured. DEFAULT MODE In this mode there is a 1:1 relationship between interfaces and WAN connections, in that an interface in default mode supports just one connection. However, unlike the multiple connection modes described below, it supports all five connection types. The figure below shows the five connection types available in ATM default mode. VLAN MUX MODE This mode uses VLAN tags to allow for multiple connections over a single interface. PPPoE, IPoE, and Bridge are supported while PPPoA and IPoA connections are not. The figure below shows multiple connections over a single VLAN Mux interface. PDF created with pdfFactory Pro trial version www.pdffactory.com
115 MSC MODE Multi-Service Connection (MSC) mode supports multiple connections over a single interface. As with VLAN Mux mode, PPPoA and IPoA connection types are not supported, while Bridging is unavailable for Ethernet WAN interfaces. After adding WAN connections to an interface, you must also create an Interface Group to connect LAN/WAN interfaces (see section G3 ~ More About MSC Mode). G1.1 ATM Interfaces Follow these procedures to configure an ATM interface. NOTE: The NEXUSLINK 3111u supports up to 8 ATM interfaces. STEP 1: Go to Advanced Setup à Layer2 Interface à ATM Interface.

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. 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 3111u can be configured to disconnect if there is no activity for a period of time by selecting the Dial on demand checkbox þ. You must also enter an inactivity timeout period in the range of 1 to 4320 minutes. PDF created with pdfFactory Pro trial version www.pdffactory.com
125 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 þ. 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 þ should not be selected to free up system resources for better performance. ENABLE FIREWALL If this checkbox þ is selected, the Security submenu will be displayed on the Advanced Setup menu after reboot. If firewall is not necessary, this checkbox þ 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 þ. 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 3.2 IP Configuration. USE STATIC IPv6 ADDRESS This option displays when IPv6 is enabled. Unless your service provider specially requires it, do not select this checkbox þ. If selected, enter the static IP address in the IPv6 Address field along with a value for Prefix Length. Don’t forget to adjust the IP configuration to Static IP Mode as described in 3.2 IP Configuration. MTU Maximum Transmission Unit. The size (in bytes) of largest protocol data unit which the layer can pass onwards. This value is 1492 for PPPoE. 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.
