Tun
Creates and configures a TUN (network TUNnel) interface on the host system. A TUN interface operates at the network layer (Layer 3) of the OSI model and emulates a point-to-point network device. It provides a virtual IP interface that allows the pipeline to send and receive raw IP packets as if they were arriving from or destined to a physical network interface. TUN interfaces are commonly used for implementing virtual private networks (VPNs), IP tunneling, and other Layer 3 routing or forwarding mechanisms, where packet-level manipulation is required. Note, see also the TAP component for Layer 2 Ethernet frame handling.
