Configuring the Optional Network
The optional network is an isolated network for less secure public
resources. Many customers use the optional network for public com-
puters such as a Web, e-mail, or FTP server. A factory default Fire-
box does not connect the trusted network to the optional network.
While you can enable traffic between these networks, this procedure
decreases security for the trusted network. For more information,
see “Adding a Policy for the Optional Interface” on page 83.
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.
Many public servers must have a static IP address. For increased
security, we recommend that you disable DHCP on the optional net-
work. If it is necessary to protect your servers from Internet traffic,
you can put your user computers on the optional network and your
servers on the more secure trusted network.
