There are numerous reasons why there are other PH> port numbers to TCP than 80 and other protocol numbers to IP than 6. Why do you think they're ignorant ? Isn't TCP over HTTP is normally used to attempt bypassing of firewalls ? IMHO Firewall/Security admins are ignorant if they don't take this into account AFAIK you can tunnel IP over(at least): 1) HTTP(not just use port 80 for non HTTP traffic) 2) ICMP ... 3) DNS queries(needs an external "custom" cooperating DNS) -- Rafi
