tun2socks creates a TUN network interface that tunnels TCP and UDP
traffic through a SOCKS5, HTTP, Shadowsocks, or Relay proxy.  It is
powered by gVisor's userspace TCP/IP stack and supports gateway mode
for transparent proxying of other devices on the network.

Features include IPv4/IPv6 support, multiple proxy protocols with
authentication, a REST API for runtime statistics, and cross-platform
compatibility with Linux, macOS, FreeBSD, OpenBSD, and Windows.
