WinTProxy

Transparent SOCKS5 proxy for Windows. WinTProxy intercepts IPv4 TCP and UDP traffic with WinpkFilter, plans each packet through explicit DNS, bypass, policy, proxy, return-path, and execution stages, then applies a proxy/direct verdict.

What It Does

• SOCKS5 TCP CONNECT and UDP ASSOCIATE forwarding
• DNS hijacking before normal policy decisions
• Ordered proxy/direct policy rules
• Fixed-size hot-path state for conntrack, DNS NAT, process lookup, and relays
• Explicit plan/execute flow with centralized send routing

Quick Start

sudo apt install gcc-mingw-w64-x86-64
cmake -B build -DCMAKE_TOOLCHAIN_FILE=cmake/mingw-toolchain.cmake
cmake --build build

Install WinpkFilter, place ndisapi.dll next to WinTProxy.exe, then run:

WinTProxy.exe --config config.example.json
