5.7 Routing Table 5.7.1 Configure Static Routing This function allows manually defined by users as the only path to the destination. Users can configure the static routing path to Broadband Router. For example: There have one pc with two interfaces in this area, one interface is connected to Broadband Router (domain A), and the other connected to another Server (domain B).
Page 52
ROUNTING TABLE Router Mode Basic NAT mode: Similar to Gateway mode, the difference is that Basic NAT mode only has Basic NAT function. Once you select Basic NAT mode, all the additional function such as DoD (Dial on Demand), IP Filter, DoS and so on will be disabled.
Dynamic Routing: Dynamic Routing allows router learns of path to destination by receiving periodic updates from others. The protocol used in communication between routers is RIP 1/2 (Routing Information Protocol). RIP1 supports only broadcast mode while RIP2 supports broadcast and multicast mode. ROUNTING TABLE 5.7.2 Current Routing Table This display shows the valid routing paths in Broadband Router.
5.8 Access Control 5.8.1 Local IP Filtering - Gateway Mode only Broadband Router allows you to do accessed restriction of block/allow outgoing IP packets by protocol ( port number). You may restrict some IPs only to perform limited protocols or allow them to execute partial protocols.
5.8.2 Remote IP Filtering - Gateway Mode only - Broadband Router provides you to do accessed restriction for users. You may restrict some destination IP address that are not allow to reach IP Address: destination IP address that prohibit users to reach Enable: enable restrict function REMORE IP FILTERING...
5.8.3 DoS Defense - Gateway Mode only - This Broadband Router also provides with DoS (Denial of Service Defense) function to protect your network servers, hosts, routers and other devices from the attacking of villain using mass data transmission. The default value in The display is the optimize parameter for Router.
Page 60
Function Description IP Fragments Checking the IP fragments. When it finds someone from WAN side Checking tries to attack your network using overlap IP fragments in a bad attention, this function will check over these packets and drop them. IP Address Finding out whether the source address(s) and destination spoofing address(s) are legal IPs or not.
5.9 Advance 5.9.1 Virtual Server - Gateway / Basic NAT Mode only - You may have FTP, MAIL or other server on your LAN. If you would like to allow the global users access some servers providing special services on your LAN.
VIRTUAL SERVER VIRTUAL SERVER For example, Supposing you want to have four servers providing FTP, HTTP, Mail and Telnet services, you must enter four virtual servers and enable them. If users key in ftp://203.74.94.30, Broadband Router will send the data of FTP protocol to the server of 192.168.1.10.
5.9.2 DMZ Host - Gateway / Basic NAT Mode only - The Demilitarized Zone (DMZ) function provides a way for public servers (Web, e-mail, FTP, etc.) to be visible to the outside world (while still being protected from DoS (Denial of Service) attacks such as SYN flooding and Ping of Death).
For example (several DMZ Hosts), if you own several legal IPs, you can assign which legal IP correspond to which IP on your LAN. This assignment will let most protocol to access the assigned IP on the LAN. DMZ HOST...
5.9.3 Multi-NAT Multi-NAT function allow you to configure multiple LAN IP Domain to each WAN port( total 10 LAN IP can be defined), after configure multiple NAT function It will act like have virtual router connect to Broadband Router LAN port, all traffic between each LAN IP domain , will send and receive through broadband router.
5.9.4 Load Balance - Gateway Mode / Basic NAT Mode only Broadband Router provides three load balance work modes: Session All the enabled WAN ports have the same (1:1) bandwidth rate. Weight round Configure the WAN ports bandwidth rate manually. robin Traffic Router will find the lowest loading WAN port to transmit and...
Weight Round Robin mode: Configure the WAN ports bandwidth rate manually, means you can Distribute each coming session from users to each WAN port, following the Rate that you assign in each WAN port. The session number in each WAN can be numbered from 1 to 100, The suggest number is under 1 ~10.

5.9.5 IP Binding (Gateway Mode / Basic NAT Mode only) In Internet world, there have some Game Server or Personal Server have special request for connection, these special request include. (1). Use special port number to perform specific function. (2). Not allow user connect with multiple IP address For Example, if user use load Balance function provide by router to connect Server, Server might response with many login display back to user, because each session comes...
5.9.6 DDNS (Gateway Mode / Basic NAT Mode only) You need to apply for a free DNS domain name from www.dyndns.org. Broadband Router will update the WAN IP address to DDNS’s database once a WAN port was connected to Internet if DDNS function is enabled. And the users in Internet can find out the Broadband Router via this domain name.
5.9.7 Configure Proxy This function work together with Mail Alert function, if there have Proxy Server in your local LAN, please fill in necessary Proxy information in this display. Some environment needs to fill in Proxy information. CONFIGURE PROXY...
5.9.8 Mail Alert - Gateway Mode / Basic NAT Mode only - Enter the Receiver/ Sender e-mail Address in the fields and check the items you want. System will send e-mails to Receiver address once the conditions meet the setting. Receiver mail address: The mail address that will receive alert mail Sender mail address: The mail address that send out alert mail, you Should fill in a legal format address...
5.9.9 Time Zone (Gateway Mode / Basic NAT Mode only) Broadband Router will obtain the GMT (Greenwich Mean Time) after connected to Internet. You need to indicate the local time so that the system could show the correct time. For example, Taiwan’s local time is GMT + 8 hours.
5.9.10 System Log Show all the records after Broadband Router Power on, such as WAN port up/down, WAN IP address, the obtained time, DDNS current corresponding WAN IP address and so forth. You can also save these data to files. SYSTEM LOG...
5.9.11 MAC Address Clone If your ISP blocked the MAC address of a network card, you may use MAC Address Clone to duplicate the MAC address to the Mac address in each WAN port. Remove all Ethernet cable on Broadband Router LAN port except for the PC you want to clone.
5.10 Firmware Update Broadband Router allows you to easily update the embedded firmware. We will occasionally provide new firmware on the web site to help you updating the firmware of your Broadband Router. Follow the procedure to update your firmware after downloaded the new code. Method 1: Run a TFTP server program such as TFTPD32.
