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 permitting packet based data transmission between 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 to traverse the first and the second firewalls. The method can also be applied to other devices, such as routers, using NAT or NAPT.
