Abstract
A remote access session is established between client and host computers with the assistance of a gateway. The gateway requests the host computer to send a plurality of data packets to different external addresses and monitors the network ports used for these outgoing packets. The gateway then uses the network port information to predict which port the host will use to transmit future outgoing data packets. A similar process is performed on the client computer. The gateway then directs the client computer to send further data packets to the network address and the predicted port of the host computer. Similarly, the host computer is directed to send further data packets to the network address and predicted port of the client computer. The computers are then directly connected together so that further data communications bypass the gateway.
