A system establishes tunnels. In response to a first request from an application, the system establishes a first tunnel between a tunneling client of a user equipment (“UE”) and a tunneling server and establishes a first outer transport layer and a first outer network layer. In response to a second request from the application, the system establishes a second tunnel between the tunneling client and the tunneling server, where the second request includes a request to use the first outer transport layer and the first outer network layer established in conjunction with the first tunnel.
