ABSTRACT:
A distributed network is provided with mobile user devices, a virtual “Virtual Private Network” (VPN) server, and a plurality of physical VPN servers, wherein the virtual VPN server allows all mobile user devices to be configured with a single VPN server address, namely that of the virtual VPN server. The plurality of physical VPM servers all recognize and intercept network traffic sent to the virtual VPN server address, so that traffic can be distributed throughout the network. Specifically, each real VPN server responds to network traffic sent by a mobile user device to the address of the virtual VPN server and communicates with the mobile user device using the virtual VPN server address in preference to the individually assigned address of the real VPN server.
