Abstract

A system and method for remote users to access a private network having a first communications protocol via a public network, such as any TCP/IP network having a second different communications protocol, in a secure manner so that the remote user appears to be connected directly to the private network and appears to be a node on that private network. A host connected to the private network may execute a host software application which establishes and provides a communications path for secure access of the remote client computer. An encrypted data stream may be communicated between the host and the client representing traffic and commands on the network.
