System and method for connecting to a device on a protected network

摘要

A novel system and method for connecting to an entity behind a firewall or proxy enhances network security and eliminates the costs and risks associated with modifying the firewall or proxy. The invention uses a trusted arbitrator as an intermediary between (1) a local area network protected by an access control mechanism such as a firewall or proxy and (2) external entities seeking to connect with an entity within the network. Requests from external entities are routed to the trusted arbitrator, which communicates with a connection entity located behind the firewall or proxy.
