Tun2Socks (Linux/Android/BSD/macOS/iOS/Windows) (IPv4/IPv6/TCP/UDP)

A simple gui for tun2socks on windows. 配合v2ray、ss等客户端(eg. v2rayN)，可使其实现tun模式。

This implements a TCP tun between a client & server using a TUN interface. The client and server communicate by encapsulating network packets within TCP connections. Encapsulation & decapsulation is Simultaneous.You can establish the tunnel in DIRECT or REVERSE mode and then use the local private ips to be used in port forward or tunnels.

Library for TUN and TAP devices over I2P in Go Applications

Beware!!! this project is still in development, it might not functional or might not work at all. Cross-platform VPN engine core supporting Xray (VMess/VLESS/Reality), WireGuard, OpenVPN, and tun drivers for Android, iOS, Windows, macOS, and Linux.

Network tunnel as an example

A mini network stack implemented using TAP Linux device. IP/ARP/ICMP/UDP parsing and generation are all supported, starting from an Ethernet frame.
