Configure the following parameters:
• LAN Protocol
The LAN protocol is set to Bridged and cannot be changed through the Web interface. If you want to
change the protocol to Routing, use the command line interface (go to
• IP Address
See the LAN administrator for a LAN IP address. Do one of the following:
– Enter an IP address for the LAN (10/100Base-T) port provided by the LAN administrator
– Use the default IP address for the LAN port, which is 10.0.0.1. If you choose to use the default IP
address, make sure the devices on your LAN are on the same subnet as this modem LAN port.
– If you want a DHCP server on your LAN to automatically provide the modem LAN port IP address,
select Client for the DHCP configuration (see
• Subnet Mask
See the LAN administrator for the subnet mask. Do one of the following:
– Enter the subnet mask for the LAN (10/100Base-T) port provided by the LAN administrator.
– Use the default subnet mask for the LAN port, which is 255.255.255.0. If you choose to use the
default subnet mask, make sure it allows devices on your LAN to access the modem LAN port.
– If you want a DHCP server on your LAN to automatically provide the subnet mask in addition to the
IP address, select Client for the DHCP configuration (see
• DHCP Client
Note:
DHCP Client mode is recommended for use only when bridging is used as the LAN
protocol.
A DHCP server must be set up and active on the LAN prior to enabling this feature. When DHCP
Client is Enabled, the modem automatically changes the LAN port IP address to all zeroes so that the
DHCP server on the LAN can immediately serve it an IP address. This parameter is used when the
LAN port is in bridging mode only.

DNS R
ONFIGURE
The DNS resolver on a DNS server maps human-readable addresses to IP address numbers. A human-readable
address is one such as:
maggie.copro.company.com
As a DNS relay, the modem forwards requests for DNS resolution to another device on the LAN or WAN that
performs the resolution service. When you enable DNS Relay mode, enter the IP address for the device that will
perform DNS resolution. Either your service provider or LAN administrator will provide this IP address.
If the modem is configured as a DHCP client (see
addition to an IP address and subnet mask. The DNS relay will be automatically enabled and the DNS server IP
address will be automatically displayed in the DNS server IP address field, as shown in
If you do not enable DNS relay nor do you enable DHCP client, then you must add the IP address for a DNS
resolver to the Internet Protocol (TCP/IP) setup for your PC (or other DHCP client). See
information on setting up this information.

If a DHCP server is not set up and active on your LAN, do not enable DHCP client.
