Use Watchguard as DNS Server

Deutsche Version

Yes, you can use a watchguard firewall as dns server, correctly as a dns forwarder.  The firewall will accept dns queries and forwards the queries to a dns server.

Unfortunately you cannot configure the dns forwarder with the web interface or the system manager. You have to use the command line interface.  You can use a SSH Client like putty on TCP Port 4118 to connect the cli or ssh on a linux shell

ssh IP-Watchguard -p 4118

You can show the dns configuration with: show ip dns

WG#show ip dns
—
— DNS Properties
—
Domain name :
DNS forwarding: Disabled
Number of server(s): 1
—
— DNS Server(s)
—
8.8.8.8

In this example is DNS forwarding disabled. To enable the feature go in the configure mode and put ip dns forwarding enable.

WG#configure
WG(config)#
WG(config)#ip dns forwarding enable

To disable DNS forwarding use no ip dns forwarding enable.
WG(config)#no ip dns forwarding enable
