Configuring the Trusted Network
You must configure your trusted network manually if you choose
not to use the Network Setup wizard.
You can use static IP addresses or DHCP for your trusted network.
The Firebox® X Edge has a DHCP server to give IP addresses to com-
puters on your trusted and optional networks. You can also change
the IP address of the trusted network.
With a factory default Firebox, its DHCP server automatically gives
IP addresses to computers on the trusted network. The trusted net-
work starts with IP address 192.168.111.1. It is a “class C” network
with a subnet mask of 255.255.255.0. The Firebox can give an IP
address from 192.168.111.2 to 192.168.111.252. The factory default
configuration uses the same DNS and domain name as it uses for
the external interface. For more information, see “IP Addresses” on
page 5.
If necessary, you can disable the Firebox DHCP server. The Firebox
can forward the DHCP requests to a DHCP server on a different net-
work. You can also use static IP addresses for the computers on your
trusted network.
