Abstract
A network device allows inbound connections from external addresses to a computer on a local network while forbidding output connections from the computer to that external address unless preceded by an inbound connection therefrom. In some embodiments, the computer is allowed to accept inbound connections from external addresses but is not permitted to initiate outbound connections to other computers in the local network unless preceded by an inbound connection. In some embodiments, a request from an external address is processed by the network device by transmitting network information for the computer to the external address and temporarily changes network rules to allow connections from the external address. In some embodiments, if the computer attempts a disallowed connection, the connection attempt is routed through a proxy server by providing network data for the proxy server to the computer.
