ADSL Gateway
Bridged Mode Only
If you are using your Gateway as a bridge, which makes the Gateway act like a stand-alone modem, select
Bridged Mode Only. All NAT and routing settings are disabled in this mode.
Optional Settings (required by some ISPs)
• Host Name and Domain Name. These fields allow you to supply a host and domain name for the Gateway.
Some 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, you can leave
these fields blank.
• MTU and Size. The MTU (Maximum Transmission Unit) setting specifies the largest packet size permitted for
network transmission. Select Manual and enter the value desired in the Size field. It is recommended that
you leave this value in the 1200 to 1500 range. By default, MTU is configured automatically.
Network Setup
• Router IP. The values for the Gateway's Local IP Address and Subnet Mask are shown here. In most cases,
keep the default values.
• Local IP Address. The default value is 192.168.1.1.
• Subnet Mask. The default value is 255.255.255.0.
• Network Address Server Settings (DHCP). Configure the Gateway's Dynamic Host Configuration Protocol
(DHCP) settings in this section.
• 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, it is highly
recommended that you leave the Gateway enabled as a DHCP server. You can also use the Gateway in
DHCP Relay mode.
• DHCP Relay Server. If you enable the DHCP Relay mode for the Local DHCP Server setting, enter the IP
address for the DHCP server in the fields provided.
• Advanced: This button displays a window that lets you reserve addresses in the DHCP range for particular
machines.
• Autodetect LAN DHCP Server: Enable this function if you already have a DHCP server on your LAN and you
wish to continue using it.
