Configuring the optional network for DHCP relay
One method to get IP addresses for the computers on the Firebox X Edge optional network is to use a
DHCP server on a different network. The Edge 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 Edge is a DHCP
Relay Agent.
