One more thing. Maybe you have a quick idea, I did not run through the docs for that.

 
Asking my DNS for a reverse address gives an authoritative answer:

 
[root at hallo ~]# nslookup

> server sixtysix 

Default server: sixtysix

Address: 192.168.94.66#53

> 192.168.94.123

Server:         sixtysix

Address:   192.168.94.66#53

 
123.94.168.192.in-addr.arpa     name = fileserver.corp.domain.de.

 
Asking pdns-recursor is a non-authoritative answer

 
 
> set port=5300

> 192.168.94.123

Server:         sixtysix

Address:   192.168.94.66#5300

 
Non-authoritative answer:

123.94.168.192.in-addr.arpa     name = fileserver.corp.domain.de.

 
Authoritative answers can be found from:

 
Any quick idea?

Bert,

 
thank you very much. That seems to be the solution for my issue. I was aware of this switch and played with it sooner, without success. But this was in another test environment, potentially with more hidden problem.

 
Great! Again, thank you!

Ok, I see it now, try adding: serve-rfc1918=off

What you are seeing is that the powerdns recursor is answering your

192.168.in-addr.arpa queries itself.
