Heh, only if you want to block traffic to your nameserver. Normal DNS traffic occurs over UDP/53, while DNS zone transfers occur over TCP/53. If you block UDP/53, you're going to stop any DNS requests from getting to BIND. If this is what you want, you'd be better off to simply disable BIND. Without knowing *what* you're trying to accomplish, it's hard for me to suggest one course of action over another. -- Jason Dixon, RHCE DixonGroup Consulting http://www.dixongroup.net -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
