Changing Your Network Settings
56 WatchGuard Firebox X Edge
4 Type the WINS Server address, DNS Server primary address, DNS
Server secondary address, and DNS Domain server suffix in the
applicable fields.
If no value is entered, the Firebox by default uses the address settings
provided to it from your service provider.
5 Click Submit.
6 Reboot the Firebox X Edge.
To configure the Firebox as a DHCP relay agent:
1 If you have not already done so, use your browser to open the
Firebox X Edge configuration pages. Select Network =>
Optional.
The Trusted Network Configuration page appears.
2 Select the Enable DHCP Relay checkbox.
3 Type the IP address of the DHCP relay server in the applicable
field.
4 Click Submit.
5 Reboot the Firebox X Edge.
The Firebox will send all DHCP requests to the specified, remote DHCP
server and relay the resulting IP addresses to the computers connected
to the trusted network. If the Firebox is unable to contact the specified,
remote DHCP server in 30 seconds, it will revert to using its own DHCP
server to respond to computers on the trusted network.
Assigning static IP addresses on the optional network
Whether or not you choose to use the Firebox X Edge DHCP server,
you can assign static IP addresses to computers on your optional
network. If you disable the DHCP server, you will have to manually
configure the IP address and subnet mask of all computers on the
optional network. You can also choose to selectively configure indi-
vidual computers with a static IP address. This is necessary, for
example, when a client-server application requires a static IP address
for the server.
To disable the Firebox X Edge DHCP server completely, clear the
Enable DHCP Server on the Optional Network checkbox on the
Optional Network Configuration page.
