Services for the Optional Network

The default configuration of the Firebox® X Edge allows all traffic

that starts in the trusted network to go to the optional network.

The default configuration of the Firebox denies all traffic that starts

in the optional network and tries to go to the trusted network.

Here are some examples of how you can use the optional network:

• You can use the optional network for servers that the external

network can get to. This helps to protect the trusted network,

because no traffic is allowed to the trusted network from the

optional network when the Firebox is in default configuration.

When computers are accessible from the external network, they

are more vulnerable to attack. If your public Web or FTP server

on the optional network is hacked or compromised, the attacker

cannot get to your trusted network.

• You can use the optional network to secure a wireless network.

Wireless networks are usually less secure than wired networks. If

you have a Wireless Access Point you can increase the security of

your trusted network by keeping the Wireless Access Point on

the optional network.

• You can use the optional network to have a different network IP

address range that is allowed to communicate with the trusted

network. See the section “Disabling Traffic Filters,” below.
