Configure a firewall interface as a DHCP client.
Before configuring a firewall interface as
a DHCP client, make sure you have configured a Layer 3 interface
(Ethernet, Ethernet subinterface, VLAN, VLAN subinterface, aggregate,
or aggregate subinterface) and the interface is assigned to a virtual
router and a zone. Configure an interface as a DHCP client if you
need to use DHCP to request an IPv4 address for the interface.
