111 6.13 Wireless 6.13.1 Basic 2.4GHz The Basic option allows you to configure basic features of the wireless LAN interface. Among other things, you can enable or disable the wireless LAN interface, hide the network from active scans, set the wireless network name (also known as SSID) and restrict the channel set based on country requirements. Click Apply/Save to configure the basic wireless options. Consult the table below for descriptions of these options.
112 Option Description Enable Wireless A checkbox  that enables or disables the wireless LAN interface. When selected, a set of basic wireless options will appear. Enable Wireless Hotspot2.0 Enable Wireless Hotspot 2.0 (Wi-Fi Certified Passpoint) on the wireless interface. Hide Access Point Select Hide Access Point to protect the access point from detection by wireless active scans. To check AP status in Windows XP, open Network Connections from the start Menu and select View Available Network Connections. If the access point is hidden, it will not be listed there. To connect a client to a hidden access point, the station must add the access point manually to its wireless configuration. Clients Isolation When enabled, it prevents client PCs from seeing one another in My Network Places or Network Neighborhood. Also, prevents one wireless client communicating with another wireless client. Disable WMM Advertise Stops the router from ‘advertising’ its Wireless Multimedia (WMM) functionality, which provides basic quality of service for time-sensitive applications (e.g. VoIP, Video). Enable Wireless Multicast Forwarding Select the checkbox  to enable this function. SSID [1-32 characters] Sets the wireless network name. SSID stands for Service Set Identifier. All stations must be configured with the correct SSID to access the WLAN. If the SSID does not match, that user will not be granted access. BSSID The BSSID is a 48-bit identity used to identify a particular BSS (Basic Service Set) within an area. In Infrastructure BSS networks, the BSSID is the MAC (Media Access Control) address of the AP (Access Point); and in Independent BSS or ad hoc networks, the BSSID is generated randomly. Country A drop-down menu that permits worldwide and specific national settings. Local regulations limit channel range: US= worldwide, Japan=1-14, Jordan= 10-13, Israel= 1-13 Country RegRev Wireless country code for transmit power limit. Max Clients The maximum number of clients that can access the router. Wireless - Guest / Virtual Access Points This router supports multiple SSIDs called Guest SSIDs or Virtual Access Points. To enable one or more Guest SSIDs select the checkboxes  in the Enabled column. To hide a Guest SSID select its checkbox  in the Hidden column. Do the same for Isolate Clients and Disable WMM Advertise. For a description of these two functions, see the previous entries for “Clients Isolation” and “Disable WMM Advertise”. Similarly, for Enable WMF, Max Clients and BSSID, consult the matching entries in this table. NOTE: Remote wireless hosts cannot scan Guest SSIDs.
113 6.13.2 Security 2.4GHz The following screen appears when Wireless Security is selected. The options shown here allow you to configure security features of the wireless LAN interface. Please see 6.13.3 for WPS setup instructions. Click Apply/Save to implement new configuration settings. WIRELESS SECURITY Setup requires that the user configure these settings using the Web User Interface (see the table below). Select SSID Select the wireless network name from the drop-down menu. SSID stands for Service Set Identifier. All stations must be configured with the correct SSID to access the WLAN. If the SSID does not match, that client will not be granted access. Network Authentication This option specifies whether a network key is used for authentication to the wireless network. If network authentication is set to Open, then no authentication is provided. Despite this, the identity of the client is still verified. Each authentication type has its own settings. For example, selecting 802.1X authentication will reveal the RADIUS Server IP address, Port and Key fields. WEP Encryption will also be enabled as shown below. Different authentication type pops up different settings requests.
114 Choosing 802.1X, enter RADIUS Server IP address, RADIUS Port, RADIUS key and Current Network Key. Also, enable WEP Encryption and select Encryption Strength. Select the Current Network Key and enter 13 ASCII characters or 26 hexadecimal digits for 128-bit encryption keys and enter 5 ASCII characters or 10 hexadecimal digits for 64-bit encryption keys. Choosing WPA2-PSK, you must enter WPA Pre-Shared Key and Group Rekey Interval. WEP Encryption This option specifies whether data sent over the network is encrypted. The same network key is used for data encryption and network authentication. Four network keys can be defined although only one can be used at any one time. Use the Current Network Key list box to select the appropriate network key.
115 Security options include authentication and encryption services based on the wired equivalent privacy (WEP) algorithm. WEP is a set of security services used to protect 802.11 networks from unauthorized access, such as eavesdropping; in this case, the capture of wireless network traffic. When data encryption is enabled, secret shared encryption keys are generated and used by the source station and the destination station to alter frame bits, thus avoiding disclosure to eavesdroppers. Under shared key authentication, each wireless station is assumed to have received a secret shared key over a secure channel that is independent from the 802.11 wireless network communications channel. Encryption Strength This drop-down list box will display when WEP Encryption is enabled. The key strength is proportional to the number of binary bits comprising the key. This means that keys with a greater number of bits have a greater degree of security and are considerably more difficult to crack. Encryption strength can be set to either 64-bit or 128-bit. A 64-bit key is equivalent to 5 ASCII characters or 10 hexadecimal numbers. A 128-bit key contains 13 ASCII characters or 26 hexadecimal numbers. Each key contains a 24-bit header (an initiation vector) which enables parallel decoding of multiple streams of encrypted data.
116 6.13.3 WPS 2.4GHz Wi-Fi Protected Setup (WPS) is an industry standard that simplifies wireless security setup for certified network devices. Every WPS certified device has both a PIN number and a push button, located on the device or accessed through device software. The NexusLink 3240 has a WPS button on the device. Devices with the WPS logo (shown here) support WPS. If the WPS logo is not present on your device it still may support WPS, in this case, check the device documentation for the phrase “Wi-Fi Protected Setup”. NOTE: WPS is only available in Open, WPA-PSK, WPA2-PSK and Mixed WPA2/WPA-PSK network authentication modes. Other authentication modes do not use WPS so they must be configured manually. To configure security settings with WPS, follow the procedures below. I. Setup Step 1: Enable WPS by selecting Enabled from the drop down list box shown. Step 2: Set the WPS AP Mode. Configured is used when the NexusLink 3240 will assign security settings to clients. Unconfigured is used when an external client assigns security settings to the NexusLink 3240. NOTES: Your client may or may not have the ability to provide security settings to the NexusLink 3240. If it does not, then you must set the WPS AP mode to Configured. Consult the device documentation to check its capabilities.
117 IIa. PUSH-BUTTON CONFIGURATION The WPS push-button configuration provides a semi-automated configuration method. The WPS button on the front panel of the router can be used for this purpose. The WPS push-button configuration is described in the procedure below. It is assumed that the Wireless function is Enabled and that the router is configured as the Wireless Access Point (AP) of your WLAN. In addition, the wireless client must also be configured correctly and turned on, with WPS function enabled. NOTE: The wireless AP on the router searches for 2 minutes. If the router stops searching before you complete Step 4, return to Step 3. Step 3: Press WPS button Press the WPS button on the front panel of the router. The WPS LED will blink to show that the router has begun searching for the client. Step 4: Go to your WPS wireless client and activate the push-button function. A typical WPS client screenshot is shown below as an example. Now go to Step 7 (part III. Check Connection) to check the WPS connection. IIb. WPS – PIN CONFIGURATION Using this method, security settings are configured with a personal identification number (PIN). The PIN can be found on the device itself or within the software. The PIN may be generated randomly in the latter case. To obtain a PIN number for your client, check the device documentation for specific instructions. The WPS PIN configuration is described in the procedure below. It is assumed that the Wireless function is Enabled and that the router is configured as the Wireless Access Point (AP) of your wireless LAN. In addition, the wireless client must also be configured correctly and turned on, with WPS function enabled. Step 5: Select the PIN radio button in the WSC Setup section of the Wireless Security screen, as shown in A or B below, and then click the appropriate button based on the WSC AP mode selected in step 2. A - For Configured mode, click the Add Enrollee button.
118 Enter STA PIN: a Personal Identification Number (PIN) has to be read from either a sticker or the display on the new wireless device. This PIN must then be inputted at representing the network, usually the Access Point of the network. B - For Unconfigured mode, click the Config AP button. Step 6: Activate the PIN function on the wireless client. For Configured mode, the client must be configured as an Enrollee. For Unconfigured mode, the client must be configured as the Registrar. This is different from the External Registrar function provided in Windows Vista. The figure below provides an example of a WPS client PIN function in-progress. III. CHECK CONNECTION Step 7: If the WPS setup method was successful, you will be able access the wireless AP from the client. The client software should show the status. The example below shows that the connection established successfully. You can also double-click the Wireless Network Connection icon from the Network Connections window (or the system tray) to confirm the status of the new connection.

RIFS Advertisement One of several draft-n features designed to improve efficiency. Provides a shorter delay between OFDM transmissions than in802.11a or g. 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. 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.
124 Field Description 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. 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. 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. Beamforming Transmission (BFR) Enable beamforming signal enhance for wireless transmission. Beamforming Reception (BFE) Enable beamforming signal enhance for wireless reception.

130 Chapter 7 Voice This chapter first describes the various options for configuration of the SIP voice service. It then provides detailed instructions for making telephone calls using VoIP (Voice over IP) or PSTN (Public Switched Telephone Network) services. Session Initiation Protocol (SIP) is a peer-to-peer protocol used for Internet conferencing, telephony, events notification, presence and instant messaging. SIP is designed to address the functions of signaling and session management within a packet telephony network. Signaling allows call information to be carried across network boundaries. Session management provides the ability to control the attributes of an end-to-end call. NOTE: The SIP standard is set by the Internet Engineering Task Force (IETF). The SIP standard defines the following agents/servers: • User Agents (UA) - SIP phone clients (hardware or software) • Proxy Server – relays data between UA and external servers • Registrar Server - a server that accepts register requests from UA • Redirect Server – provides an address lookup service to UA The following subsections present Basic, Advanced and Debug SIP screens. Each screen provides various options for customizing the SIP configuration.
131 7.1 SIP Basic Setting – Global Parameters A common parameter setting.  Bound Interface Name: Select a WAN interface to send SIP control messages. IP Address Family: Select to use IPv4 or IPv6 for VoIP messages.

141 7.7 Telephone Calls To make a call, simply dial the number. The dial plan (i.e. the dialed digits) is normally customized for each installation. The default dial plan allows for dialing of 4-digit extensions or direct IP addresses. For shorter extension numbers (e.g. 3-digits) adding a “#” at the end. When a Call Server (SIP Proxy Server) is configured into the system, the dialed digits are translated and routed by the Call Server to the correct destination as registered with the Call Server. If no Call Server is configured, calls can still be made using 4-digit extensions, rather than using full IP addresses. The originator translates the dialed-digits to a destination device as follows: First Digit: Line identifier (for multi-line gateways) Remaining digits: Host number part of an IP address. The Network number part is considered to be the same as the caller’s IP address. For example, if a caller at address 10.136.64.33/24 dials “2023”, the call will be placed to the second line at address 10.136.64.23. All devices have to be on the same Class C subnet (24-bit subnet mask). To dial an IP address directly, dial the IP address digits using * on the keypad as the dot. Complete the address with a final * or #. When using IP address dialing it is not possible to specify which line at a gateway is called, so the gateway always routes IP-address dialed calls to the first line. Network busy tone (fast busy) will be played for unknown or unreachable destinations. To answer a call, pick up the phone or press the hands free button. Caller ID The Call Manager delivers Calling Number when placing calls. The calling number is transmitted to the analog line for CLASS recognition. Call Hold To put a call on hold, press flash then hang up (optional). To return to the original call, press flash or pick up the phone. The phone will issue a short ring burst every 30 seconds or so while on-hook to remind you that a call is on hold. Call Transfer • To transfer a call, press flash then dial the new number. • To transfer immediately, hang up (blind transfer). • To transfer with consultation, wait for the party to answer, consult, and hang up. • To abort the transfer (if the third party does not answer); press flash to return to the original call. Conference Calling To turn a two-party call into a three-party conference call, press flash and dial the third party. Wait for the party to answer, then press flash. To drop the third party and return to a two-party call, press flash again. To drop yourself out of the conference, hang up. The call will be transferred (so that the other two parties remain connected to each other). In conference mode, the conference initiator performs the audio bridge/mixing function – there are only two voice streams established.
142 Call Waiting If call waiting is enabled on a line, and you hear the call waiting tone during a call, press flash to answer the second call. The first call is automatically placed on hold. To switch between calls, press flash again. • To disable the call waiting feature, dial *60. • To enable the call waiting feature, dial *61. Call forward feature settings (Busy or All) takes priority over the call-waiting feature. The call-waiting feature is ignored on new incoming calls if there is already a call on hold or in conference. Call Forward Number • To set the call forward number, dial *74 then the number. Note that this does not actually enable forwarding; to do so, select the call forward action as described below. • To disable all call forwarding features, dial *70 Call Forward No Answer • To enable call forward on no answer, dial *71. Incoming calls will be forwarded if unanswered for 18 seconds. Call Forward Busy • To enable call forward if busy, dial *72. Incoming calls will be immediately forwarded if the phone is off-hook. Call Forward All • To enable call forward for all calls, dial *73. • To disable the “forward all calls” feature, dial *75. Previous settings for Call Forward Busy or No Answer are not modified. Call Return • To call the last known incoming caller (unanswered or not), dial *69. Redial • To redial the last outgoing number, dial *68. VoIP to PSTN • To dial a regular phone call over PSTN, you must first dial ##.

166 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.
167 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.
168 DAYTIME PARENTAL CONTROL This feature restricts access of a selected LAN device to an outside Network through the NexusLink 3240, 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.

190 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 3240 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 IP Configuration. FIXED 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.
191 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 3240 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.
