Changing Your Network Settings
56 WatchGuard Firebox X Edge
work. A factory default Firebox has the trusted network and the
optional network on 2 different subnets.
To change the IP address of the optional 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 > Optional.
The Optional 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 optional network
The DHCP Server option sets the Firebox X Edge to give IP addresses
to the computers on the optional network. When the Firebox
receives a DHCP request from a computer on the optional network,
it gives the computer an IP address. A factory default Firebox has
the DHCP Server option for the optional interface off.
