Stunning is an alternative for stunnnel written all in Golang. It's a lib that help you to tunnel different type of network traffic.
So far Tcp, Udp, Tls, Http and Https tunnels are implemented and You can use Tcp Socket, Socks5 and Tun Device as your interface.
In future it's planned to add Udp Socket and Serial interfaces and a terminal for monitoring.
There are test written for socks and tcp sockets and more tests would be added in future.
Helps would be appreciated! :)
