Abstract

A method and system is provided for establishing a connection between a first terminal connected to a router in a first-network environment and a second terminal in a second-network environment. In one embodiment, a connection is established from the first terminal to a server that lies outside of the first-network environment. The first terminal then transmits a packet to the server through the router. The server then determines the IP address and port number utilized by the router to transmit the packet to the server. This IP address and port number is then transmitted to the second terminal, which then establishes a connection to the first terminal.
