Ethernet hubs or switches with RJ-45 connectors to connect more
than seven computers. It is not necessary for the computers on the
trusted network to use the same operating system.
To add more than seven computers to the trusted network:
1
Make sure that each computer has a functional Ethernet card.
2 Connect each computer to the network. Use the procedure
"Connecting the Edge to more than seven devices" on page 20.

Configuring the Optional Network

Th e optional network is an isolated network for less secure public
resources. By default, a Firebox® does not allow traffic from the
optional network to get to the trusted network. The factory-default
settings do allow traffic that starts from the trusted network to get
to the optional network, but you can restrict that traffic. See "Ser-
vices for the Optional Network" on page 116 to see how to do this.
Because traffic that is started from the optional network is usually
not allowed to the trusted network, you can use the optional net-
work for servers that other computers can connect to from the
Internet, such as a web, e-mail, 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 Internet, the attacker cannot 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
Edge's system configuration 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 can also
change the IP address range of the optional network.
If you make any changes to the optional network configuration
page, you must click Submit and then restart the Firebox before the
new configuration starts. You can make many changes, and then
restart just once when you are done.
