Lynwood,
The question that occurs to me is why do you have your DNS server exposed to the network when likely no one is using it? It's not listed in the NS records for the zones and so the only way to make use of your server is to explicitly configure it as a server (in resolv.conf or its equivalent), which, excuse me, I doubt very many people have done. - Brian

Does anyone currently use tcp AXFR to copy 44.IN-ADDR.ARPA. or AMPR.ORG. from me?
My apologies if this is really obvious, but I hope you are aware that TCP is also used for general DNS queries, not just zone transfers, Cheers, Borja EA2EKH
