[Pdns-users] PDNS does not send info for reverse DNS

[abang]

In addition to Peter's hint:

I assume your dig is asking your Recursor on Port 53. So you have to advise the Recursor to forward queries for your local zones to your authoritative server on Port 5300.

Try this in the rcursor.conf:

forward-zones=10.in-addr.arpa=127.0.0.1:5300
