Log the traffic from the firewall before you drop it, and see what's being dropped.
Alternately, while DNS is trying to resolve, use netstat to see what ports are open on the machine which is trying to resolve an address. Netstat will work on Linux or on legacy Windows boxes, so you should be able to see what ports are needed. Some switches might be different, but the command is there for both OSes.
