Abstract

The present invention provides an access gateway, a device gatewayand a relay server for aiding an establishment of a network connection between a first computer having a first network address on a first network and a second computer having a second network address on a second network. An access gateway can actively establish a network route in the first computer and can forward traffic between the first computer and a relay server via a first persistent connection. A device gateway can connect to the second computer and can forward traffic between the second computer and the relay server via a second persistent connection. A relay server according to the invention can maintain persistent connections with an access gateway and a device gateway and can relay traffic between the two persistent connections.
