HevSocks5Tproxy is a simple, lightweight transparent proxy for Linux.
Features
- IPv4/IPv6. (dual stack)
- Redirect TCP connections.
- Redirect UDP packets. (UDP over TCP)
Linux:
git clone --recursive git://github.com/heiher/hev-socks5-tproxy
cd hev-socks5-tproxy
makeAndroid:
mkdir hev-socks5-tproxy
cd hev-socks5-tproxy
git clone --recursive git://github.com/heiher/hev-socks5-tproxy jni
cd jni
