About changing the IP address of the trusted network
If necessary, you can change the trusted network IP address. For example, if you connect two or more Firebox
X Edge devices in a virtual private network, each Edge must use a different trusted network address. If the two
sides of the VPN use the same trusted network IP addresses, one side must change the trusted network IP
address range so that it is different from the other side. For more information, see What you need to
create a VPN.
Change the IP address of the trusted network
To change the IP address of the trusted network:
1. To connect to the System Status page, type
https:// in the browser address bar, followed by the IP
address of the Firebox X Edge trusted interface.
The default URL is: https://192.168.111.1
2. From the navigation bar, select Network > Trusted.
The Trusted Network Configuration page appears.
3. Type the new IP address of the Firebox X Edge’s trusted interface in the IP Address text field.
4. If necessary, type the new subnet mask.
If you change the IP address of the Firebox X Edge trusted interface, you must use the new IP address
in your browser address bar to connect to the Edge’s web management interface. For example, if
you change the Firebox X Edge trusted interface IP address from the default 192.168.111.1 to
10.0.0.1, then you must use https://10.0.0.1 to connect to the Firebox X Edge. Your computer’s IP
address must also be changed so that it is in the new trusted network IP subnet range.
