Name	Type	Description
ExtIpv4TunDevice	simple module	This module provides a bidirectional connection to a real TUN device of the host computer which is running the simulation. It writes the packets arrived on 'lowerLayerIn' gate to the specified real TUN device, and sends out packets arrived from real TAP device on 'lowerLayerOut' gate.
