¾ DHCP Relay: Select Relay, then you will see the next screen (shown in Figure 4-13), and the
Router will work as a DHCP Relay. A DHCP relay is a computer that forwards DHCP data
between computers that request IP addresses and the DHCP server that assigns the
addresses. Each of the device's interfaces can be configured as a DHCP relay. If it is enabled,
the DHCP requests from local PCs will forward to the DHCP server runs on WAN side. To
have this function working properly, please run on router mode only, disable the DHCP server
on the LAN port, and make sure the routing table has the correct routing entry.
