Wireless Broadband Router User Manual 20 4.3 Configuration for NAT Routing Mode Prior to configuring your Wireless Broadband Router, you must decide whether to configure the device as a router or as a bridge. This section only describes how to set up the device to act as a router. For bridge configuration, see ”4.4 Configuration for Bridge Mode” for instructions. When operating as a router, the device communicates with your ISP through the WAN port. Depending on the connection type offered by your ISP, you may get the WAN IP address by one of the following means: • DHCP Client: In this connection type, your router acts as a DHCP client and requests IP information from the DHCP server on the ISP side. Select this option if your ISP assigns you with a dynamic IP address each time you log on. • PPPoE Client: Some ISPs use a PPPoE session to make connection with their clients. If this is the case, you should enable this option and finish the PPPoE Client settings. The WAN port of the device will be assigned a public IP address from your ISP’s server. • PPTP Client: This router supports VPN (Virtual Private Network) pass-through for both PPTP (Point-to-Point Tunneling Protocol) and IPSec (IP Security). VPN allows corporations to extend their own corporate network through private "tunnels" over the public Internet. Effectively, a corporation uses a wide-area network as a single large local area network. A company no longer needs to lease its own lines for wide-area communication but can securely use the public networks. • Manual Config: If your ISP assigns you a fixed IP address, you should select this option and manually enter the IP information provided by your ISP. Different configuration items will be displayed depending on your connection type. Consult with your ISP which option applies to you
4. Web Configuration 21 and obtain related information for correct configuration. Then proceed to finish the following procedures.
Wireless Broadband Router User Manual 22 WAN Configuration for NAT Routing Mode Click WAN in the configuration menu to enter the WAN configuration page and carry out the procedures below. Part 1. Configuring general settings. 1. In the WAN/LAN Relation item, select the NAT Routing option. This option allows the device to act as a router and use the built-in NAT function to translate your multiple private IP addresses to a single public IP address. However, only outgoing requests are allowed to pass through the device unless you specify otherwise. Outside users cannot see your private local IP addresses. This leaves your home or business network hidden from outside intruders. 2. In the Protocol item, select a protocol type according to the connection type offered by your ISP. 3. If required, in the MAC Address field, enter your network adapter’s MAC address in the format of xx:xx:xx:xx:xx:xx. Otherwise just keep the default values. This field allows you to clone a network adapter’s MAC address to the WAN port of the router. Some ISPs use the MAC address of NIC, which was connected to your Cable/ADSL modem, for static mapping and thus give you the same IP address each time the Cable/ADSL modem requests for IP address for the Ethernet port. If this is the case, this feature removes the need of asking your ISP to change the registered MAC address and you can still use the same given IP for the router’s WAN port. 4. In the Host Name field, you may supply a host name for this router if this is required by your ISP. Some ISPs only respond to a DHCP request with a valid “Host Name”. If a host name is not necessary for your ISP, just leave it blank.
4. Web Configuration 23 Part 2. Configuring protocol settings According to the connection type you selected above, proceed to set up related parameters. υ DHCP Client If DHCP Client is your option, no other configuration is needed. You may just click Apply to end your WAN settings. After the connection to your ISP is established, the information provided by your ISP will be displayed in the Status group. Figure 4-4 WAN Configuration-DHCP Client υ PPPoE Client If PPPoE Client is your option, configure these fields as required by your ISP. PPPoE Connection Status: This item is not configurable. It displays whether the connection is up or down. Username/Password: Enter the username and password provided by your ISP used to log on to Internet connection. Connection Mode: Select your PPP connection from these options: Keep Alive: This feature will keep your PPPoE-enabled Internet connection always alive. This is done by sending echo requests periodically to ISP to prevent the connection from being terminated by ISP.
Wireless Broadband Router User Manual 24 Connect on Demand: If enabled, the router will trigger a PPP session for connection to the Internet if any client PC on your LAN sends out a request for Internet access. However, the router automatically disconnects the PPP session after the WAN connection has been idle for the amount of time you specified in the Max Idle Time box. If your Internet account is billed based on the amount of time of your Internet connection, you probably want to enable this option and enter an idle time value best suitable for your network. Manual Connect: If enabled, the system administrator can manually connect or disconnect the PPP session by clicking the Connect/Disconnect buttons in this page. MTU/MRU: Allows you to adjust the Maximum Transmission/Receive Unit in bytes for the WAN interface. You may need to adjust the values to a smaller size if the servers of your ISP do not support full size frame packets. The packets larger than the specified values will be fragmented and the performance may therefore be influenced. It’s suggested not to modify the MTU/MRU settings unless instructed by your ISP. After you finish the WAN settings, click Apply to submit your changes. Figure 4-5 WAN Configuration-PPPoE Client
4. Web Configuration 25 υ PPTP Client If PPTP Client is your option, configure these fields as required. Username/Password: Enter the access credentials, i.e., username and password, for the router to initiate a PPTP connection to the PPTP server. Server IP Address: Enter the IP address of the PPTP server. IP Address/Subnet Mask: Enter the Internet IP address/subnet mask that the ISP assigns to this router for reaching the PPTP server. Idle Disconnect: If checked, enter the amount of time the router will maintain the PPTP connection to when there is no traffic. Figure 4-6 WAN Configuration-PPTP Client
Wireless Broadband Router User Manual 26 υ Manual Conifg If Manual Config is your option, configure these fields as required by your ISP. IP Address/Subnet Mask: Enter the fixed IP address and subnet mask given by your ISP in respective fields. The default values are 0.0.0.0/0.0.0.0. Default Gateway: The IP address of the default gateway of the router. It is the IP that the router first contact to communicate with the Internet. The default is 0.0.0.0. DNS Servers: Specifies the IP address of the Domain Name Server. Your LAN side DHCP clients use the DNS to map a domain name to its corresponding IP address and vice versa. Up to three DNS servers are allowed. If no DNS server is specified or the specified servers are not available, the router will automatically assign a DNS server to the DHCP clients. WINS Servers: Optional for Windows Internet Names Service. Enter the IP addresses of WINS servers if required. Host Name & Domain Name: Optional. Allows you to supply host and domain name for the router. After you finish the WAN settings, click Apply to submit your changes. Figure 4-7 WAN Configuration-Manual Config
4. Web Configuration 27 LAN Configuration for NAT Routing Mode Your router communicates with your LAN through its LAN port. The LAN configuration page allows you to define the private IP address and DHCP server settings over the LAN interface. 1. In Manual Config > IP Address & Subnet Mask field, enter the IP address and subnet mask for the LAN port. By default, the IP address and subnet mask of the LAN port is 192.168.1.1 and 255.255.255.0 respectively. Note that if you change the private IP address and apply the changes, the PC from which you configure the router will lose the communication to the router. To reconnect, you will need to renew the IP address of the PC or change to an IP address compatible with the new LAN port IP address. 2. In DHCP Server > Service field, select whether to enable DHPC service on the LAN port. The Wireless Broadband Router implements a built-in DHCP (Dynamic Host Configuration Protocol) server on its LAN interface, which dynamically assigns IP addresses to the DHCP clients on the LAN/WLAN. The DHCP server also provides a default gateway (the router’s LAN IP address) and DNS addresses for DHCP clients to access the Internet. DHCP function spares you the hassle of manually assigning a fixed IP address to each PC on the LAN/WLAN. It is probably you already have a DHCP server on your network and you do not enable this function. DHCP server is enabled by default. Note: It is not allowed to have two DHCP servers running on one LAN at the same time. If you decide to enable the DHCP on this router, remember to disable the DHCP function of the other device. If you disable DHCP server, just click Apply to submit your changes. Otherwise proceed to next step. 3. If DHCP server is enabled, enter the fields below: DHCP Lease Time: Specify the time that a network device can lease a private IP address before the DHCP server reassigning the IP address. IP Pool Range: Specify the starting and ending IP address of the IP address pool. Whenever a network device requests an
Wireless Broadband Router User Manual 28 Internet session, the router will allocate an unused IP address from this pool and lease them to the device for a specified amount of time. Figure 4-8 LAN Configuration in Router Mode Viewing Current DHCP Assignments When DHCP server function is enabled for your LAN, the router keeps a record of any machine (either Ethernet or Wireless node) that has leased IP from the specified IP pool. The DHCP lease table is displayed under System Overview > LAN Interface: Figure 4-9 DHCP Lease Table
4. Web Configuration 29 4.4 Configuration for Bridge Mode A bridge connects two or more LANs together and bases the forwarding decision on the MAC address.

Wireless Broadband Router User Manual 32 4.5 Wireless LAN (2.4G) Configuration The Wireless Broadband Router implements Access Point capability which connects wireless clients to a wired LAN. It allows wireless nodes to access network resources and share the broadband Internet connection. With the default values, the router (Access Point) can be easily associated by a wireless client. We suggest that you customize the wireless settings to prevent unauthorized association. υ Basic Configuration Access Point Name: The name used for identifying the Access Point. SSID: Service Set ID. It uniquely identifies a logical network domain name of your WLAN. The default value is IEEE 802.11 LAN. Network Type: An “Open” AP will periodically broadcast its SSID to allow the wireless clients to recognize their presence. However, this creates a security hole since any wireless station with SSID set to “any” or got the broadcast may associate to your AP. It is recommended to set this option to Closed to have your AP only accept stations whose SSID are the same as this AP. Country: Select the country where you use this AP. When the country setting is changed, the AP scans only the legal frequency channels allowed in that regulatory domain. Channel ID: The radio frequency used for communication. Available channels vary according to the regulations in the country you specified in the Country drop-down list. Select a channel out of the available cannels or use the default channel. υ Security Data Encryption (WEP Mode): WEP (Wired Equivalent Privacy) is an authentication algorithm which encrypts your data and protects your Wireless LAN against eavesdropping.
4. Web Configuration 33 WEP is disabled by default. If you want to protect your data when it is transferred from one station to another, you should enable this security option. For security concern, we strongly suggest you enable WEP function. To enable WEP, select 64 bits or 128 bits option as the encryption algorithm. The higher the bit number, the greater the complexity and the security of the encryption. Authentication Mode: Authentication is a process in which the AP validates if wireless clients are qualified to access the AP’s service. This happens prior to any wireless client can associate to an AP. The IEEE 802.11b defines two types of algorithms in authentication: the “Open System” and “Shared Key”. With Open System, the authentication is done through a pseudo process, accepting all kinds of requests, mainly used in cases where connectivity is more important than security. Shared Key, on the other hand, utilizes WEP capability to further verify if the wireless client is authorized to share this AP’s resource. If the client has the wrong key or no key, it will fail authentication and will not be allowed to associate with the AP. If you select Open System or Shared Key, wireless stations can communicate with or without data encryption. WEP Keys: Enter one to four WEP keys in either ASCII or Hexidecimal format. Note that when using Hexidecimal format, only digits 0-9 and letters A-F, a-f are allowed. Valid key length for each encryption type is as below: HEX Format ASCII Format 64 Bit 10 hexadecimal digits 5 ASCII characters 128 Bit 26 hexadecimal digits 13 ASCII characters Aside from entering your WEP keys, you should select one of the four keys to encrypt the data before being transmitted. The AP always transmits data encrypted using this WEP Key. The key number (1,2,3,4) is also transmitted. The receiving station will use the key number to determine which key to use for decryption. If the key value does not match with the transmitting station, the
Wireless Broadband Router User Manual 34 decryption will fail. To ensure successful decryption, have your wireless stations set identical key tables. Note: All Wireless Stations must use identical encryption algorithm level and Key values (same key position in its key table) to ensure successful data transmission. υ Access Control MAC Address Access Control: The device also supports authentication based on the MAC address of a wireless client. If this function is enabled, the AP will allow association by a client only if that client's MAC address matches an address in the Allow List. To enable this function, select the Enable option and then manually key in MAC address in the Allow List. Up to 16 MAC entries are allowed. υ Advanced Configuration We suggest you not to modify the Advanced parameters unless specific requirement is required. The parameters are described as below: Beacon Interval: Defines the periodic interval at which the 802.11 WLAN Access Point sends out a beacon. RTS Threshold: Request to send threshold. It specifies the packet size beyond which the AP invokes its RTS/CTS mechanism. Packets that exceed the specified RTS threshold trigger the RTS/CTS mechanism. Fragment Threshold: It determines whether packets will be fragmented and at what size. On an 802.11 wireless LAN, packets exceed the fragmentation threshold are fragmented, i.e., split into, smaller units suitable for the circuit size. On the other hand, packets smaller than the specified fragmentation threshold value are not fragmented. DTIM: Specifies the Deferred Traffic Indicator Map (DTIM) period. This value determines at which interval the AP will send the next
4. Web Configuration 35 DTIM when the AP has buffered broadcast or multicast messages for associated clients. Its clients hear the beacons and awaken to receive the broadcast and multicast messages. The default value is 3. Rate: Sets the rate of data transmission according to the speed of your wireless network. You can select from a range of transmission speeds (from 1 to 54 Mbps) or keep the default setting, Auto, to have the AP automatically use the fastest possible data rate and enable the auto-fallback feature. Basic Rate Set: Sets what data rate control and management frames will be transmitted at. The Default option uses 1 or 2 Mbps for 802.11b and 6, 12 or 24Mbps for 802.11g. The All option uses 1, 2, 5.5, 6, 11, 12, 18, 24, 36, 48, or 54Mbps. 54g Mode: Allows you to choose the 54g mode between 54g Auto, 54g Performance and 802.11b Only.

4. Web Configuration 37 4.6 Filters When your Wireless Broadband Router operates as a router, the built-in NAT function provides your LAN with the Internet access via the single public IP of the WAN port. That means all network devices are allowed to access various Internet service. Under this circumstance, network security becomes an important issue and system administrators may need to build access control to protect the network. The filter feature serves as a basic firewall security measure for your network. When filter function is enabled, the Wireless Broadband Router inspects all data packets arrive from LAN side and determines if packets are allowed to pass through the WAN port depending on whether packets match your filter rules and whether your filter type is Listed Pass or Listed Block. In addition to filter settings, the Filters page also allows to configure other firewall settings, including WAN Management, WAN Port Ping Reply and Report Log to TFTP Server. Specifing Your IP Filter Rules If you are going to specify your filter rules, follow the procedures below: 1. In the Firewall item, select the Enable option. 2. In the Filter Type item, select the action (Listed Pass or Listed Block) to be performed on the IP packets matching your filter rules. 2. In the four filter types, select whether to enable or disable each filter. 3. If a filter is enabled, enter the criteria in provided fields. Click More to add more criteria if required. See next section for more information. 4. Click Apply to commit your changes.
Wireless Broadband Router User Manual 38 Filter Types When setting up filter rules, you can define the Filter rules based on the LAN machine’s MAC address, IP address or the protocol type of the data packet. Each filter type is described as below. Note: Based on OSI reference model, MAC Filters demand higher priority than IP Filters while IP Filters higher than Port Filters. MAC Filters: The MAC address of the LAN machine from which packets are allowed (or prohibited) to pass through the WAN port. Up to 12 entries are allowed. IP Filters: The range of IP addresses of the LAN machines from which packets are allowed (or prohibited) to pass through the WAN port. You may enter the same address in both (Start and End) fields to define a single IP address. Up to 5 entries are allowed. TCP Port Filters: Allows (or prohibits) certain LAN machine to use TCP based service in the specified port range through the WAN port. Up to 12 entries are allowed. For example, to allow (or prohibit) local PC 192.168.1.210 to use FTP service (using TCP port 21): IP Address Start End 192.168.1.210 20 21 UDP Port Filters: This field allows you to allow (or prohibit) certain LAN machine to use UDP based service in the specified port range through the WAN port. Up to 12 entries are allowed. For example, to allow (or prohibit) local PC 192.168.1.210 to use ping service (using UDP port 53): IP Address Start End 192.168.1.210 53 53
4. Web Configuration 39 Filter Scenario of the Wireles Broadband Router When setting up your firewall policy, note the filter scenario used by the router: When Filter Type is Listed Block: If all the filters are disabled: No filter rule is specified to block any packet. All packets can pass through the WAN port. (Defaults) If any filter is enabled: only the packets matching the specified rule are blocked; other packets can pass through the WAN port. When Filter Type is Listed Pass: If all the filters are disabled: No filter rule is specified to allow any packet to pass. All packets are blocked. If any filter is enabled: Only the packets matching the specified rule can pass; other packets are blocked. Figure 4-14 Filters
Wireless Broadband Router User Manual 40 Viewing Filter Log When filter feature is enabled, the router will keep a record of the packets discarded. To view the firewall activity log, go to System Overview > Firewall > Activity Log and click the Show Log button. Filter activity log is displayed in a separate window with a maximum of 32 entries. Clicking the Update button allows to refresh the log with newly reported data. The log types are defined as below: Type Description 1 Blocked packets, from WAN side, by DoS (Deny of Service) protection mechanism. 2 Blocked packets, from LAN side, by MAC/IP/TCP/UDP filter. Other Firewall Settings WAN Management: Available only when Firewall is enabled. If available, this item is disabled by default that rejects any external access from the WAN port. If this option is enabled, a WAN Port filed is displayed with the default value 80. If required, you may enter another port number used by the external WAN access. If WAN Management is enabled using a non-80 port, the router’s HTTP service (Web Configuration Utility) will be accessible via the router’s WAN port IP address following by a colon and the non-80 port: http://<WAN IP address>:<non-80 port> For example, if 1234 is entered, the router will be accessible at http://203.1.2.3:1234 where 203.1.2.3 indicates the WAN port’s IP address. If WAN Management is enabled using standard port 80, no suffix is required. If WAN Management is enabled using port 80, your publicly accessible Web server (if any) on LAN side should use a non-80
4. Web Configuration 41 HTTP port. And you need to use the Forwarding feature to shift external HTTP requests to the non-80 port number used by the Web server on LAN side. WAN Port Ping Reply: Available only when Firewall is enabled. If available, this setting determines if an external host will get reply when trying to ping the IP address of your WAN port. It’s disabled by default. Report Log to TFTP Server: Available only when Firewall is enabled. If available, it specifies whether to report firewall event log to your TFTP server. If enabled, a LAN TFTP Server field is present for you to specify the IP address of the TFTP server. All the filter logs are sent to TFTP server although only 32 entries are displayed in Show Log window (see System Overview page).
Wireless Broadband Router User Manual 42 4.7 Forwarding This page allows you to configure the Forwarding and DMZ (De-Militarized Zone) features. Unlike Filter which governs outgoing traffic, Forwarding is used to provide external access to your local machines. This is commonly used when you have publicly accessible virtual servers on your local network. By default, forwarding entry is empty and any external access to your LAN is blocked. Once you define a forwarding entry, incoming packets (identified by its port number) that match your Forwarding criteria will be forwarded to the port range of the specified local machine. Otherwise packets are blocked. Forwarding serves as a measure of security that protect your network from hazardous packets. However, if you designate a DMZ sever, incoming packets that do not match the forwarding criteria will be redirected to the DMZ IP address. That is, forwarding demands a higher priority than DMZ. Setting Up Forwarding Entries To set up your forwarding entries, enter these fields: DMZ IP Address: DMZ setting allows a local machine to be exposed to the Internet. If you specify a DMZ host here, all virtual services requests not specified in the Forwarding table are forwarded to the DMZ host. TCP Port Forwards: In the first Start and End fields, define the port range for the incoming TCP service you want to forward. In the IP Address filed, enter the IP address of the virtual server to which packets are forwarded. The Start/End fields on right side defines the port range for the TCP service on the virtual server. For example, you have a virtual server 192.168.1.210 running FTP service and you allow external access by the setting below:
4. Web Configuration 43 Start End IP Address Start End 20 21 192.168.1.210 20 21 UDP Port Forwards: The configuration is the same as setting TCP Port Forwards, only that the entry applies to UDP service. When the router gets outside TCP/UDP requests destined for the WAN port, it determines whether the services are allowed according to your forwarding settings. For example, if you do not specify FTP virtual service in Forwarding table, incoming FTP requests (identified by port number in packets) are blocked or otherwise sent to DMZ host (if specified). On the other hand, if an FTP forwarding entry has been set up, the FTP requests will be able to be forwarded to the specified machine. If you have a Web server on your network… If you enable WAN Management (i.e., allow external access from the WAN port, see “4.6 Filters” ) and want to designate another Web server on your local network, take either of the procedures below to avoid port confliction: Option 1: In Filters page, with WAN Management enabled, enter a port number other than 80 (for example, 1234) and reserve the number 80 for your Web server. If any external host wants to access your Web management server through the WAN port, it should use the address below: http://204.71.200.143 (i.e., the WAN IP address):1234 Option 2: Have WAN Management to use the standard port number 80 and your Web server (e.g., 192.168.1.4) to use another port number (e.g., 8080). In this case, you need to shift the incoming HTTP request (destined for local Web server) to port 8080 of your Web server, the forwarding entry may look like this: Start End IP Address Start End 8080 8080 192.168.1.4 8080 8080
Wireless Broadband Router User Manual 44 With the settings above, an external host trying to access your local Web server should use the address like this: http://204.71.200.143 (i.e., the WAN IP address):8080 If you do not enter the suffix “:8080”, the external host’s packets will contain the standard port number 80 and the router will not forward the packets since no forwarding entry matches. As a result, if a WAN computer tries to access the LAN’s Web server, it will turn to access the Web service on the WAN port, i.e., the Web Configuration Utility of the router instead. Figure 4-15 Forwarding
4. Web Configuration 45 4.8 Administration υ System Clock Configuration Network administrators may want to synchronize date and time among network devices. This can be done by synchronizing the local clock to an available NTP server or manually specifying the date and time in this router for your network. Option 1: Using an existing NTP server. 1. In Set by item, enable the Network Time Protocol option. 2. In NTP Server field, enter the IP address of the NTP server. 3. In Update Interval item, select your update interval as 1, 2 or 7 days. 4. In Time Zone field, select a time zone according your geographic location. Option 2: Specifying the router as your network NTP server. 1. In Set by item, enable the Manual Setup option. 2. Manually enter the date and time information in respective fields. υ Management Setup Username&Password: For administration security, specify required User Name and Password and re-enter password in corresponding field for confirmation. This setting limits your Web-based manager access to users with the correct credentials. By default, the user name is empty and the password is admin. υ Firmware Upgrade This option allows you to upgrade the Wireless Broadband Router with new firmware. After upgrading, your customized configuration will still exist and not reset to the factory defaults. To upgrade, download required firmware file to your host PC and follow the steps below:
Wireless Broadband Router User Manual 46 1. In the Locate New Firmware field, click Browse to locate the firmware file. 2. Click the Upgrade button to start upgrade and then wait for a few minutes as the utility prompts. You will return to the Administration page while the process is complete. Note: Do not interrupt the upgrade process otherwise it might cause damage to your Wireless Broadband Router. After upgrade, you can see the new firmware version in Current Firmware version field. υ User Configurations Save Current Configurations: Allows you to save your customized settings to the device. Once your router is properly configured, you may wish to save current settings. The saved settings can be retrieved easily if required, even after you reload factory defaults. Retrieve User Configurations: If you have loaded factory defaults (either via the Load Default button on the back panel or via the Restore button in this group), you can restore your settings by clicking the Retrieve button. Restore Factory Defaults: To restore factory defaults, click the Restore button and then wait for a few minutes as the utility prompts. You will return to the Administration page while the process is complete. This feature is basically the same as resetting via the Load Default button (see “Rear Panel and Connectors”) on the device but it allows you to remotely perform the reset task. υ System Reboot: This option allows to you remotely reboot the device.
