For the LAN and WAN RIP Direction, select the direction you want RIP (Routing
Information Protocol) activated in
Routing mode. See “Routing” on page 71 for more
information on RIP.

DHCP can be enabled only when routing is enabled. If you select DHCP Enable
when routing is not enabled, the modem deselects DHCP Enable when you
click Submit. If you disable routing, the modem deselects DHCP Enable when
you click Submit.
Select DHCP Enable to enable the modem to act as a DHCP server to automatically
assign IP addresses to devices on the LAN. If you select DHCP, ensure that all
devices on the LAN have the TCP/IP stack set to
obtain an IP address automatically
(see “Setting Up the PC to Access the Modem Web Pages” on page 27).
The modem automatically enters the
Start IP Address for the first device on the LAN
as one address higher than the Ethernet port on the modem with DHCP enabled.
