5.2.3.1 DHCP Mode
You can configure your network and the router to use the Dynamic Host Configuration Protocol (DHCP). This screen allows you to select the DHCP mode that this router will support.
There are two different DHCP modes: DHCP Server and DHCP Relay. When the router is acting as a DHCP server, configure it on the DHCP Server screen; while acting as a DHCP relay, you can set up the relay on the DHCP Relay screen.
5.2.3.2 DHCP Relay
Some ISPs perform the DHCP server function for their customers’ home/small office network. In this case, you can configure this device to act as a DHCP relay agent. When a user’s computer on your network requests Internet access, the router contacts your ISP to obtain the IP configuration, and then forwards that information to the computer.
