Configuring DHCP Relay

{ XE "DHCP relay:Configuring the device as" }Some ISPs perform the DHCP server
function for their customers' home/small office networks. In this case, you can configure the
device as a DHCP relay agent. When a computer on your network requests Internet
access, the ATU-R130 contacts your ISP to obtain an IP address (and other information),
and then forwards that information to the computer.
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).
Next, you 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, and then click
in the task bar.
The DHCP Relay Configuration page{ XE "DHCP Relay Configuration page" }{ XE
"Pages:DHCP Relay Configuration" } displays, as shown in Figure 19.

3. Type the IP address of your ISP' s DHCP server in the fields provided.
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.
