Hi Martin, The zone name is the following for both servers.
Zone name: 1.10.in-addr.arpa. I am using zone forwarders. With forward first enabled though it should try and return an answer from the local DNS, it clearly does not though. The only time I receive the local record is when forwarding is disabled.

Hall of Innovation Inductee <https://www.youtube.com/user/BlackDuckSoftware> Hello, we need more info: do you use global forwarders, or zone forwarders? how your reverse zones are configured (name, delegation)? Default forwarding policy is first, IMO both of your examples with forwarding enabled are forwarding first policy. Martin -- Martin Basti
