You don't need these rules at all, if you're allowing state ESTABLISHED,RELATED packets. The packets coming from your nameservers (in response to your DNS requests) will be allowed via connection tracking. The above rules would be used in the case when you want to allow incoming connections, which you probably don't need to accept from your nameserver. good times, Vineet -- http://www.doorstop.net/ -- "Computer Science is no more about computers than astronomy is about telescopes." -- E.W.
