Sophos XG internal Active Directory DNS Server for local Domain DNS resoultion - dont work


I have the following problem.

We have two Active Directory Windows DNS servers on the internal LAN. They have entered the Sophos XG Firewall as a DNS server as a forwarding.

The Sophos XG Firewall itself queries public DNS servers on the WAN.

So far everything is working smoothly.

The problem is that I would like to store the two internal Windows DNS servers for the Active Directory domain in the Sophos XG. So that when I create FQDN clients in the Sophos XG, which are resolved via internal local domain DNS.

I remember that you could do that with Sophos UTM.

I have now created the internal Active Directory domain and the internal Windows DNS servers under Network -> DNS -> “DNS host relay”.


When I create an FQDN host in Sophos XG, it is not resolved.

Can anyone help or does anyone have an idea?

Thank you
