Configuring DHCP Server

Note

By default, the device is configured as a DHCP server, with a

predefined IP address pool of 10.0.0.4 through 10.0.0.15 (subnet

mask 255.255.255.0). To change this range of addresses, see

“Viewing, modifying, and deleting address pools” on page 50.

First, you must configure your PCs to accept DHCP information

assigned by a DHCP server:

1. Open the Windows Control Panel and display the computer's

Networking properties. Configure the TCP/IP properties to

"Obtain an IP address automatically" (the actual text may

vary depending on your operating system). For detailed

instructions, see the Quick Start chapter, “Part 2 —

Configuring Your Computers.”

Next, you define the pools of IP addresses you want to make

available for distribution to your computers. These addresses can

be multiple public addresses that you have purchased from your

ISP, but are typically private addresses that you create. (LAN

administrators often create private IP addresses for use only on

their networks. See “Overview of NAT” on page 55.)

2. Launch Configuration Manager, click

DHCP Server in the

LAN tab.

The DHCP Server Configuration page displays:

Figure 15. DHCP Configuration Page

Each pool you create displays in a row on the table on this

page.

You can create up to eight pools; however, most users will

need to create only one for their LAN.

3. To add an IP address pool, click

The DHCP Server Pool – Add page displays.
