What happens to the new voice and video services for example ? That's been going on for years. Back when it was common for ISPs to run squid servers and transparently proxy to them (probably around 2000), I ran into a customer using some sort of aviation data in real time app which used port 80 (and wasn't HTTP). I had to special case traffic to that service's IP to get it not to hit squid. When I asked them why they were running a non-HTTP protocol on 80/tcp, the answer was "that gets us through most firewalls." ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
