Abstract

A VPN handler of a client device is described that provides VPN connectivity by automatically creating multiple split VPN tunnels that provide direct access to different VPN concentrators of an enterprise based on specific resources requested by the client device. A local VPN concentrator normally used by the client device may provide the VPN handler with a resource list that provides a mapping of the resources of the enterprise network to the multiple VPN concentrators that have been deployed to provide secure access to those resources. The local VPN concentrator may dynamically update the resource list on the client device so as to control the construction and use of the split VPN tunnels by the VPN handler based on changes to the enterprise network. The split tunnel approach may be transparent to applications executing on the client device and may be easily deployed to the client devices of the enterprise.
