Abstract

A tunneling system and method is described for traversing firewalls, NATs, and proxies. Upon a request from a device on the secure private network or on a public network such as the Internet, a connection to a designated or permitted device of the secure private network by way of the public network can be established, allowing selected devices of the private network to access devices on the public network. A bi-directional channel can be established where information such as rich multimedia and real-time voice and video can be accessed or communicated.
