If the Firebox cannot connect to the DHCP server in 30 seconds, it
uses its own DHCP server to give IP addresses to computers on the
trusted network. You must enable the DHCP Server on the trusted
network for the DHCP relay function to operate.
Using static IP addresses for trusted computers
You can use static IP addresses for some or all of the computers on
your trusted network. If you disable the Edge DHCP server and you
do not have a DHCP server on your network, you must manually
configure the IP address and subnet mask of each computer. For
example, this is necessary when a client-server software application
must use a static IP address for the server. Static IP addresses must
be on the same network as the Firebox trusted interface. Computers
on the trusted network with static IP addresses must use the Fire-
box’s trusted interface IP address for the default gateway.
To disable the Firebox DHCP server, clear the Enable DHCP Server
on the Trusted Network check box on the Trusted Network Config-
uration page and click Submit .

Computers on the trusted network must use the Firebox’s trusted
interface IP address as the default gateway. If a computer does
not use the Firebox as the default gateway, it usually cannot get
to the external network or the Internet.
Adding computers to the trusted network
You can connect as many as seven computers to the trusted inter-
face of the Firebox X Edge if you connect each computer to one of
the Edge’s Ethernet ports 0 through 6. You can use 10/100 BaseT
