DHCP Server

• If Enabled, the Wireless ADSL Router will allocate IP Addresses

to PCs (DHCP clients) on your LAN when they start up. The de-

fault (and recommended) value is Enabled.

• If you are already using a DHCP Server, this setting must be

Disabled, and the existing DHCP server must be re-configured to

treat the Wireless ADSL Router as the default Gateway. See the

following section for further details.

• The Start IP Address, Finish IP Address and Lease Time fields

set the values used by the DHCP server when allocating IP Ad-

dresses to DHCP clients. This range also determines the number of

DHCP clients supported.

See the following section for further details on using DHCP.

What DHCP Does

A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to a

DHCP Client (PC or device) upon request.

• The client request is made when the client device starts up (boots).

• The DHCP Server provides the Gateway and DNS addresses to the client, as well as

allocating an IP Address.

• The Wireless ADSL Router can act as a DHCP server.

• Windows 95/98/ME and other non-Server versions of Windows will act as a DHCP client.

This is the default Windows setting for the TCP/IP network protocol. However, Windows

uses the term Obtain an IP Address automatically instead of "DHCP Client".

• You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If your

LAN does not have other Routers, this means there must only be one (1) DHCP Server on

your LAN.)

Using the Wireless ADSL Router's DHCP Server

This is the default setting. The DHCP Server settings are on the LAN screen. On this screen,

you can:

• Enable or Disable the Wireless ADSL Router's DHCP Server function.

• Set the range of IP Addresses allocated to PCs by the DHCP Server function.

You can assign Fixed IP Addresses to some devices

while using DHCP, provided that the Fixed IP Addresses

are NOT within the range used by the DHCP Server.

Using another DHCP Server

You can only use one (1) DHCP Server per LAN segment. If you wish to use another DHCP

Server, rather than the Wireless ADSL Router's, the following procedure is required.

• Disable the DHCP Server feature in the Wireless ADSL Router. This setting is on the

LAN screen.
