Milan Technology MIL-W0311 Dhcp, What DHCP Does, Using the Wireless Gateways DHCP Server, Chapter

Chapter 5	5
DHCP

This Chapter covers the use of DHCP, using either an existing DHCP Server or the Wireless Gateway's DHCP Server function.

Overview

If your LAN does not use DHCP, and you do not wish to use DHCP, you can ignore this chapter.

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 boots.

•The DHCP Server provides the Gateway and DNS addresses to the client, as well as allocating an IP Address.

•Windows 95/98/ME include all the software required to act as a DHCP client. This is the default Windows setting for TCP/IP. However, Windows uses the term Obtain an IP Ad- dress automatically instead of "DHCP Client".

•The Wireless Gateway can act as a DHCP server.

Using the Wireless Gateway'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 Gateway'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. If you wish to use another DHCP Server, rather than the Wireless Gateway’s, the following procedure is required.

1.Disable the DHCP Server feature in the Wireless Gateway. This setting is on the LAN screen.

2.Configure the DHCP Server to provide the Wireless Gateway’s IP Address as the Default Gateway.
