Configuring DHCP Relay

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 ADSL Barricade contacts your ISP
to obtain an IP address (and other information), and then forwards
that information to the computer. Follow the following instructions
to configure DHCP relay.
