Abstract

A proxy server shares a plurality of modems connected to a wide area network among multiple client computers connected to a local area network. Each of the client computers on the local area network is assigned a local address while each of the plurality of modems is assigned a modem port address valid on the wide area network. In one embodiment, a processor controls address substitution allowing multiple client computers to share modems when communicating to host computers in a wide area network. The processor creates a descriptor list to keep track of the connections between the client computer and host computers on the wide area network and uses the descriptor list to determine to which client computer an incoming data packet should be sent. The processor also creates a proxied application list to determine if an outgoing data packet, received from one of the client computers, is one to be proxied through the proxy server.
