BEFORE YOU BEGIN. . .
Your network administrator will:
❑ Determine if you will use the modem Ethernet port in full- or half-duplex mod e .
❑ Identify a subnet value, including IP addresses and subnet masks.
❑ Determine if DHCP for the modem is enabled. If it is enabled, determine if th e modem will
be configured as a:
– DHCP client which receives an IP address fr om another device that is a DHCP server
on the LAN
3
– DHCP server (determine the range of IP addresses the modem will need to serve, and
identify the DHCP gateway and DNS server)
– DHCP relay agent (determine the IP address to which the DHCP functions will be
relayed)

• Enter an IP address for the LAN (10Base-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, ensure that 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 DHCP
Client below).
Subnet Mask
See the LAN administrator for the subnet mask. Do one of the following:
• Enter the subnet mask for the LAN (10Base-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, ensure that 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 below).
DHCP Client
If a DHCP server is not set up and active on your LAN, do not enable DHCP
client. 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.

Default Lease Time
The default amount of time, in seconds, that a device on the LAN can be
bound to the IP address it was served before the lease expires. This value is
provided by your LAN administrator.
Max Lease Time
The maximum amount of time, in seconds, that a device on the LAN can be
bound to the IP address it was served before the lease expires. This value is
provided by your LAN administrator.
DHCP Default Gateway
Enter the IP address of the DHCP default gateway that is provided by the
LAN administrator for devices on the LAN. After you configure this IP
address, the modem provides this IP address as a default DHCP gateway to
requesting DHCP clients (such as PCs) on the LAN. If there are no gateways
on the LAN, then the modem LAN port IP address can be assigned as the
gateway.
DHCP DNS Server
Enter the IP address of the Domain Name System (DNS) server that will
translate human-readable addresses to IP addresses. The DNS server can be
either on the LAN or the WAN side of the modem. The modem provides this
IP address as a default DNS server to requesting DHCP clients (such as PCs)
on the LAN. If the DNS server is on the LAN side of the modem, acquire the
IP address from your LAN administrator. If the DNS server is on the WAN
side of the server, acquire the IP address from the service provider.
If you enabled DNS relay on page 16 and entered a DNS server IP address,
then enter the modem LAN port IP address as the DHCP DNS server.
