About DHCP relay agents

One way to get IP addresses for the computers on the trusted or optional networks is to use a DHCP server on a different network.

The Firebox can send a DHCP request from a DHCP client to a DHCP server at a different location through a

VPN tunnel. It gives the reply to computers on the trusted or optional network. This option lets computers in more than one office use the same network address range. In this procedure, the Firebox is a DHCP relay agent.

You must set up a VPN tunnel between the Edge and the DHCP server for this feature to operate correctly.
