Ok, You're setting up an authorative server which uses a local recursor
as a forwarder.

Have you tried 'dig @localhost -p 5300' for results on the queries?

If you have no specific need for the authorative server I'd suggest
disabling that and running the recursor on port 53.

I'd remove the file /etc/powerdns/pdns.d/pdns.recursors as this sets up
a dns proxy to the router possibly overwriting the previous setting in
pdns.conf.

Hope this helps.
