Bind and firewall

where would that be set? The outside wold sends a request to port 53 of
216.68.75.194 (sorry put the old IP in previose post. That is the correct
one.) Those should be forwarded to the internal IP of the same port and a
response sent. According to the firewall admin it is not blocking outgoing
ports so that should not be the problem. Can I telnet to that port and issue
commands to the server? If so what commands do I use? The firewall is a
BigIP load balencer by f5 networks, in case anyone knows of a problem with
them.

Do you have the option 'query-source * port 53' configured?
