Well, at least for my @home host, cox has decided that I'm not smart
enough to filter errant packets by myself.  Soo, inbound smtp and www
are filtered out.  I've run up the support tree to level 2 and even
got a special code red coping center hotline, but all of them had zero
clue as to actual filtering going on.

TOS Compliance Statement: Not that I had a webserver or smtp server
mind you, but it's right funny to watch the firewall burn packets.
