Configuring the Trusted Network
User Guide 51
Changing the IP address of the trusted network
If necessary, you can change the trusted network address. For exam-
ple, if you connect two or more Firebox devices in a virtual private
network, each Firebox must use a different trusted network address.
For more information, see “What You Need to Create a VPN” on
page 107.
To change the IP address of the trusted network:
1 To connect to the System Status page, type the IP address of
the trusted network in the browser.
The default IP address is: https://192.168.111.1
2 From the navigation bar, select Network > Trusted.
The Trusted Network Configuration page appears.
3 Type the first address of the new network address range in the
IP Address text field.
4 If necessary, type the new subnet mask.
Most networks use 255.255.255.0 which includes 252 addresses.
Using DHCP on the trusted network
The DHCP Server option sets the Firebox X Edge to give IP addresses
to the computers on the trusted network. When the Firebox receives
a DHCP request from a computer on the trusted network, it gives
the computer an IP address. A factory default Firebox has the DHCP
Server option for the trusted interface on.
