GreenTunnel is a network utility designed to bypass website restrictions imposed through Deep Packet Inspection by internet service providers. It runs a local proxy that modifies how connection information is transmitted to prevent hostname-based filtering. For HTTPS connections, it fragments the TLS ClientHello message so the requested hostname is not contained in a single packet. It also supports TLS record splitting and configurable fragmentation delays. Encrypted DNS resolution through DNS over HTTPS or DNS over TLS helps avoid DNS-based blocking. The application can automatically configure system proxy settings and restore them when it stops. Users can operate it through a graphical desktop application, command-line interface, or Docker container. GreenTunnel does not hide the user's IP address or function as a VPN.
