GOTUN

TUN devices are a type of virtual network device that allow programs to easily simulate network behavior. TUN simulates a three-layer device, and allows for the processing of data from the network layer. GOTUN provides a cross-platform TUN device interface for processing IP datagrams on different platforms.
