we have a Watchguard XTM 22 with firmware version 11.4.1. Is it possible to use the device as DNS server which translate the DNS requests from the internal clients? We assign the internal IP address of the Watchguard as default gateway and as primary DNS Server on the clients. With this configuration the clients did not become any DNS responses. If we use another (public) DNS server all is fine and the translation work.
How can we configure the DNS forwarding service on the XTM appliance (if it is possible)?
Thanks in advance!
