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 Quick Start, Configuring Your Computers
on page 15. Next, specify the IP address of the DHCP server
and select the interfaces on your network that will be using
the relay service.
2. Log into the Configuration Manager, click the [LAN] tab.
Then click [DHCP Relay] in the task bar. The [Dynamic
Host Configuration Protocol (DHCP) Relay Configuration]
page appears:

3. In the [DHCP Server Address] fields, type the IP address
of your ISP's DHCP server. If you do not have this number,
it is not essential to enter it here. Requests for IP information
from your LAN will be passed to the default gateway, which
should route the request appropriately.
4. Select your WAN interface from the drop-down list and
click [Add]. Your WAN interface may be named [ppp-0],
[eoa-0], or [ipoa-0]. Contact your ISP if you are unsure
which type of WAN interface you use.
