Abstract
Currently data transmission over the Internet between two client computers where both client computers are protected by firewalls is problematic, since firewalls block incoming packets. A method is provided for identifying the firewalls protecting a first client computer C1 protected by a first NAPT or NAT firewall and a second client computer C2 protected by a second NAPT or NAT firewall and allowing communications between the computers to traverse the first and the second firewalls.
