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 computer protected by a first NAPT or NAT firewall and a second computer protected by a second NAPT or NAT firewall to traverse the first and the second firewalls. The method includes the first and second computers sending first and second data packets to a designated recipient computer. The designated recipient computer communicates the first external address from the first data packet to the second computer and also communicates the second external address from the second data packet to the first computer. The second computer subsequently sends a data packet to the first external address and the first computer sends a data packet to the second external address.
Actuellement, la transmission de données sur l'Internet entre deux ordinateurs clients, les deux ordinateurs clients étant protégés par des pare-feu, est problématique étant donné que les pare-feu bloquent les paquets entrants. L'invention concerne un procédé destiné à permettre à une transmission de données par paquets entre un premier ordinateur client C1, protégé par un premier pare-feu NAPT ou NAT, et un second ordinateur client C2, protégé par un second pare-feu, NAPT ou NAT, de traverser les premier et second pare-feu. Le procédé peut aussi être appliqué à d'autres dispositifs tels que des routeurs à l'aide de NAT ou NAPT.
