What type of access??
Attempted zone transfers??
Do you wish to block off all dns incomming traffic? The you could use:

ipfw add 10 deny log tcp from any to "yourhost" in via
"your_interface_connected_to_internet"
ipfw add 11 deny log udp from any to "yourhost" in via
"your_interface_connected_to_internet"

Are you using a "default to accept" configuration?
You better change that, or I'll guess that you willl forget a lot of rules.


Best regards

Christian
