Abstract

A VPN gateway device is able to assign, manage, and terminate a large volume of connections from apps executing on devices, enabling a large scale per-app VPN mobile environment. When a mobile device user opens an app on a mobile device, a VPN gateway transmits a unique IP address to the app. The gateway also transmits an app federation cookie to the app. The app shares the app federation cookie with a second app. The VPN gateway then assigns the second app the same unique IP address. The gateway then transmits a range of ports to the first app. The app uses a port in the range of ports for data transmission from the device to the VPN gateway. The gateway receives a data transmission from the first app via a VPN and determines that the data transmission originated from the first app based on the source port.
