Abstract:
1. A method comprising: discovering, by a gateway router, a server in a local area network, wherein the gateway router discovers the server by sending a universal plug and play (UPnP) message identifying the gateway router as a gateway router with access configurable by the server, wherein the gateway router sends the UPnP message only through a dedicated physical server port; receiving, by the gateway router, a response from the server, wherein the response identifies the server as a server that desires to establish external access; determining, by the gateway router, whether the server is a trustworthy server, wherein determining comprises comparing information received by the server with a stored list of trustworthy servers; configuring, by the gateway router, a logical port to forward incoming connection requests to the server; and forwarding, by the gateway router, incoming connection requests to the server.
