over the same LAN. If you mix computers with different operating
systems on your network, they pass traffic through the Firebox X
Edge to access the Internet.
To add more computers to the trusted network:
1 Verify each additional computer has an Ethernet card installed.
2 Connect each computer to the network the same way you did in
“Cabling the Firebox X Edge for more than seven devices” on
page 18. Restart each computer.
3 Set the computers to obtain their addresses using DHCP.
4 Turn off and start each computer.
Configuring the Optional Network
The optional network extends the protection of the firewall to
include telecommuters on a separate network. Users on both the
optional network and the trusted network have protected access to
the Internet, but only the optional network has access to the corpo-
rate network. Communication between the optional network and
the trusted network are denied by default, although you can enable
traffic between the two networks, as described in “Filtering Outgo-
ing Traffic to the Optional Network” on page 69. Note, however,
that enabling this traffic removes the security between the two net-
works.
As with the trusted network, you can use either the Firebox® X
Edge’s internal DHCP server or you can use static addressing on the
optional network. You can also change the IP address range of the
optional network.
Normally, if you have servers on your optional network, you should
disable DHCP and use static IP addressing. If your servers need to be
secure from Internet traffic, you may want to put your users on the
optional network with DHCP enabled and your servers on the
trusted, more secure network.
Enabling the optional network
1 Type the IP address of the optional network in your browser
window to connect to the System Status page of the Firebox X
Edge.
The default IP address is: https://192.168.111.1
