ABSTRACT:
A server including a dual channel communications module operable to establish a communication session between the server and a client is provided. The server may be operable to receive a dual channel communication packet from the client. In a particular embodiment, the dual channel communication packet may include a header in a data payload. The header includes a client external IP address, and the data payload includes an encoded port command having a client internal IP address and a client data port number. A codec operable to decode the port command may also be provided. The server may also include a translation module for retrieving the client external IP address from the header. In a particular embodiment, the server is operable to establish data channel coordinates including the client external IP address, the client data port number, a server internal IP address and a server data port number.
