DHCP Server

This page allows you to enable DHCP server on LAN interface and then your router can assign IP addresses to those
PCs connected to your router.
The ADSL Router implements a built-in DHCP (Dynamic Host Configuration Protocol) server, which dynamically
assigns IP addresses and DNS server to the PCs on the LAN. DHCP function spares you the hassle of manually
assigning a fixed IP address to each PC on the LAN. It is probably you already have a DHCP server on your network
and you do not enable this function. By default the DHCP Server is enabled on private LAN interface
(192.168.100.0).
Choose the Enabled radio button and click Configure to get advanced settings. Enter the requiring information and
click Apply to invoke the configurations that you set. Below is the web page for setting DHCP server.
