System and method for secure dual channel communication through a firewall

A communication system comprising:

• a first peer comprising:
• a communications module operable to receive a dual communication packet from a second peer over a first channel, the dual communication packet including a header having a second peer external IP address and a data payload having an encoded port command having a second peer internal IP address and a second peer data port number;
• a codec operable to decode the encoded port command;
• a translation module operable to retrieve the second peer external IP address from the header and to generate a modified port command including the second external IP address;
• and
• the system operable to establish a second channel based on the modified port command.

A method for communicating between a first peer and a second peer, the method comprising:

• receiving, at the second peer, an IP Packet from the first peer, the IP packet including a header and a port command;
• the header including a first IP address of the first peer and the port command including an encoded second IP address of the first peer;
• decoding the encoded second IP address of the first peer;
• retrieving the first IP address of the first peer from the header;
• generating a modified port command including the first IP address of the first peer in place of the second IP address of the first peer;
• and
• using the modified port command to establish a data socket between the first and second peers.
