13.3.2 DHCP
The following screen will appear if you select Advanced > LAN > DHCP from the main menu. This screen
contains the settings that control how your modem interacts with local devices connected to it. It is recommended
that these settings not be changed. If you change the settings in this screen, click save and then OK. If you click
reset or Cancel, the screen will return to its previous settings.
Your modem’s Dynamic Host Configuration Protocol (DHCP) server makes it possible to easily add computers that
are configured as DHCP clients to the home network. It provides a mechanism for allocating IP addresses and
delivering network configuration parameters to DHCP clients. A client (host) is a device connected to a network.
A client sends out a broadcast message on the LAN requesting an IP address for itself. The modem’s DHCP server
then checks its list of available addresses and leases a local IP address to the client for a specific period of time. It
simultaneously designates this IP address as “taken,” and the client keeps this IP address for the duration of the
lease.
NOTE: If you want to disable the DHCP server in the modem, uncheck the check box next to Enable DHCP
Server. Westell recommends that you do not change these settings unless your ISP instructs you to do so.
DHCP Server Click this drop-down menu to select the DHCP (Dynamic Host Control Protocol)

• Off: DHCP Server is disabled.
• Private LAN: DHCP addresses will be saved into the Private LAN
configuration.
• Public LAN: DHCP addresses will be saved into the Public LAN
configuration. This option is only available when Public LAN DHCP
server is enabled.
DHCP Start Address (if
DHCP is enabled)
Displays the start of the IP address pool that the modem uses to assign IP addresses
to local devices. Start Address must be within the IP address and lower than the
DHCP End Address (any number from 0-254). By default, DHCP Start Address is
set to 192.168.1.15.
DHCP End Address (if
DHCP is enabled)
Displays the end address of the IP address pool that the modem uses for automatic
configuration of local devices. End Address must be within the IP address and
higher than the DHCP Start Address (any number from 0-254). By default, DHCP
