DHCP Server

You can disable or enable the DHCP (Dynamic Host Configuration Protocol) server or enable the router’s

DHCP relay functions. The DHCP protocol allows your router to dynamically assign IP addresses to PCs

on your network if they are configured to obtain IP addresses automatically.

To disable the router’s DHCP Server, check

Disabled

and click

Next,

then click

Apply.

When the DHCP

Server is disabled you will need to manually assign a fixed IP address to each PCs on your network, and

set the default gateway for each PCs to the IP address of the router (by default this is 192.168.1.254).

To configure the router’s DHCP Server, check

DHCP Server

and

click

parameters of the DHCP Server including the IP pool (starting IP address and ending IP address to be

allocated to PCs on your network), lease time for each assigned IP address (the period of time the IP

address assigned will be valid), DNS IP address and the gateway IP address. These details are sent to

the DHCP client (i.e. your PC) when it requests an IP address from the DHCP server. Click

Apply

to

enable this function. If you check “

Use Router as a DNS Server

”, the ADSL Router will perform the

domain name lookup, find the IP address from the outside network automatically and forward it back to

the requesting PC in the LAN (your Local Area Network).

If you check

DHCP Relay Agent

and click

server which will assign an IP address back to the DHCP client in the LAN. Use this function only if

advised to do so by your network administrator or ISP.

Click
