Wireless-G ADSL Gateway with 2 Phone Ports
DNS Proxy
If the PCs on your network are enabled with DNS, enable the DNS Proxy to foward the DNS entries.
Optional Settings
Some of these settings may be required by your ISP. Verify with your ISP before making any changes.
Host Name/Domain Name. These fields allow you to supply a host and domain name for the Router. Some ISPs, usually cable ISPs, require these names as identification. You may have to check with your ISP to see if your broadband Internet service has been configured with a host and domain name. In most cases, leaving these fields blank will work.
MTU. MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for Internet transmission. The default setting, Manual, allows you to enter the largest packet size that will be transmitted. The recommended size, entered in the Size field, is 1492. You should leave this value in the 1200 to 1500 range. To have the Router select the best MTU for your Internet connection, select Auto.
Network Setup
The Network Setup section changes the settings on the network connected to the Router’s Ethernet ports. Wireless Setup is performed through the Wireless tab.
Router IP
This presents both the Router’s IP Address and Subnet Mask as seen by your network.
Network Address Server Settings (DHCP)
The settings allow you to configure the Router’s Dynamic Host Configuration Protocol (DHCP) server function. The Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address to each computer on your network. If you choose to enable the Router’s DHCP server option, you must configure all of your network PCs to connect to a DHCP server (the Router), and make sure there is no other DHCP server on your network.
Local DHCP Server. A Dynamic Host Configuration Protocol (DHCP) server automatically assigns an IP address to each computer on your network for you. Unless you already have one, you should leave the Gateway enabled as a DHCP server.
DHCP Relay Server. If you have a local DHCP server that you would like to use instead, enable the DHCP Relay mode for the Local DHCP Server setting and enter the IP address of the DHCP server.
