Building from source

Due to tun2socks based on gVisor, so only x86_64 and ARM64 was supported for now. Other architectures may become available in the future.

Dependencies

Make sure the following dependencies are installed:

• Go 1.15+

Building

Build and install the tun2socks binary:

make tun2socks
sudo cp ./bin/tun2socks /usr/local/bin

Build for all architectures:

make all-arch

Known Issues

Due to the implementation of pure Go, the memory consumption is higher than the previous version. If you are sensitive to it, please go back to v1.

TODO

• Windows support
• FreeBSD support
• OpenBSD support
