Configuring the Optional Network
Th
e
optional network is an isolated network for less secure public resources. By default, a Firebox® X
Edge does not allow traffic from the optional network to get to the trusted network. The factory default
settings allow traffic that starts from the trusted network to get to the optional network, but you can
restrict that traffic. For more information, see “Configuring Policies for the Optional Network” on
page 100.
Because traffic that is started from the optional network is usually not allowed to the trusted network,
you can use the optional network for servers that other computers can connect to from the Internet,
such as a web, email, or FTP server. We recommend you isolate your private network from these servers
because the public can connect to them. If a server on the optional network is attacked from the Inter-
net, the attacker cannot use it to get to the computers on the trusted network. The trusted network is
the most secure location for your private network.
If your computer is on the optional network, you can connect to the Firebox X Edge system configura-
tion pages using the optional interface IP address. The default URL for the System Status page from the
optional network is: https://192.168.112.1.
You can use the Firebox X Edge DHCP server or you can use static IP addresses for computers on the
optional network. You also can change the IP address range of the optional network.
