Realy strange. Ok let's try step by step.

Does your authoritative DNS Server work? Log-in into your DNS Server and

dig -p 5300 @127.0.0.1 -x 10.20.0.4
dig -p 5300 @127.0.0.1 -x 10.20.1.4
dig -p 5300 @127.0.0.1 -x 10.20.2.4

And please provide the whole output.

If this works, test your Recursor. Also on the same DNS Server, try

dig @10.20.0.4 -x 10.20.0.4
dig @10.20.0.4 -x 10.20.1.4
dig @10.20.0.4 -x 10.20.2.4

Also provide the whole output.

If this works, do the same on your clients:

dig @10.20.0.4 -x 10.20.0.4
dig @10.20.0.4 -x 10.20.1.4
dig @10.20.0.4 -x 10.20.2.4
