Configuring the optional network for DHCP relay

One method to get IP addresses for the computers on the Firebox
optional network is to use a DHCP server on a different network.
The Firebox can send a DHCP request to a DHCP server at a different
location and transmit the reply to the computers on the 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.
