3.4.2.2.2 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 enable, 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.
