When I query pdns and it can not answer, so it passes the query on to pdns-recursor, which then responds with the answer but then pdns discards the packets. What did I do wrong? I have tried this with the firewall both on and off and the result is the same. Below is a snippet of the log file with the error, followed by my configuration for the recursor and pdns itself. The host is a PowerPC computer running ubuntu 14.04 LTS.

Hi,

We start with pdns_recursor and then forward some to pdns. We had your
setup with pdns_recursor behind pdns and had some issues with pdns >= 3.
According to the developers that is not really supported. I do not know
if what is happening to you is similar.
