By default, I block all ip traffic to the network where this particular host resides, so I want to install a a more specific rule earlier in the chain that preferably defines the port numbers on both the inbound and outbound packet (ie. port 25 and corresponding "ack" response flags on ports > 1024) Thanks for any help! -Gary P.S. Also, is there a FAQ (besides the FreeBSD faq) for this mailing list? I'm a new member. -- garyb@fly.com
