Abstract
In some implementations, a method for routing communication includes determining a binding interface for a communication session based on a forwarding information base (FIB) and a destination for the communication session. The communication session is from an application running on user equipment (UE), and the binding interface is included in a virtual private network (VPN) tunnel established through an Internet Protocol (IP) security (IPsec) interface. Whether to filter the communication session is determined based on which perimeter of the UE includes the binding interface and which perimeter of the UE includes the IPsec interface.
