A tun2socks implementation written in Go.
If you're looking for an easy to use
tun2socksimplementation for iOS, you might be interested inleafandileaf.leafimplementstun2socksand it's written in Rust, with significantly less memory usage and significantly better performance compares to the Go version.
To run the tun2socks command line program, depending on OS, you may need to run it as root, create the TUN interface and/or configure IP address of the interface manually. Moreover, you should add corresponding routes to the routing table manually. Mind that you often want to use some different system DNS resolvers, and your proxy server should support UDP.
To use go-tun2socks as a library in your own project, refer to the following files/repos for some ideas:

- https://github.com/eycorsican/go-tun2socks-mobile

It's recommended to write your own SOCKS layer. For example, you can create a "tun2shadowsocks" program by implementing a Shadowsocks handler, see https://github.com/Jigsaw-Code/outline-go-tun2socks/tree/master/shadowsocks
It's also recommended to write your own TUN layer to connect the TUN interface and go-tun2socks, see https://github.com/eycorsican/go-tun2socks/tree/master/tun for examples.
The following projects are using go-tun2socks:
Create an ssh SOCKS proxy:
ssh -D 1234 -C -N user@example.comCreate a tunnel:
sudo tun2socks -proxyServer 127.0.0.1:1234 -routes 10.0.0.0/8,172.16.0.0/12 -exclude example.com,10.0.0.1 -loglevel debugWindows build requires a https://www.wintun.net dll located in the tun2socks executable path.
FreeBSD requires gmake package to be installed and executed.
