You mentioned that you have an access-list allowing port 53 for tcp or udp but the
question is are you filtering the response that is coming back from the DNS server.
Do you have access-lists filtering traffic coming from that direction? It will be
responding to a dynamic port number (it's destination won't be 53, it'll be whatever
your computer decides) so I don't know a way to include that into an access-list
unless you can force your computer to always use a certain port when performing DNS
queries (which is something that I don't know how to setup).
