Before configuring a firewall interface
as a DHCP relay agent, make sure you have configured a Layer 3
Ethernet or Layer 3 VLAN interface and that you assigned the interface
to a virtual router and a zone. You want that interface to be able
to pass DHCP messages between clients and servers. Each interface
can forward messages to a maximum of eight external IPv4 DHCP servers and
eight external IPv6 DHCP servers. A client sends a DHCPDISCOVER
message to all configured servers, and the firewall relays the DHCPOFFER
message of the first server that responds back to the requesting
client.
