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 Gateway 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 Gateway’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 Gateway’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 Gateway, 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.
