Abstract
Techniques described herein convert mobile traffic between different types of VPN protocols, including IP and Transport. In an embodiment, a security proxy associated with a server receives a packet associated with a client app on a device, the packet including a source identifier and a destination identifier. The security proxy reassigns a tunnel identifier as the source and a node identifier as the destination, then stores a correlation of the tunnel identifier, the source identifier, and the destination identifier. The security proxy forwards the packet to the node inside the security proxy, and determines the destination identifier based on the correlation. The node then forwards the packet to the destination. This allows for multiple devices to use a same source identifier, e.g., same IP address. In some embodiments, a secure connection is established and/or the device and server are mutually authenticated prior to the processing of the packets.
