    UDP OpenVPN Server tls SNI VPS

    Value Added OpenVPN over SNI via SNI injection SSL/TLS Tunnel

    How It Works [Android Device] │ │ OpenVPN TCP/UDP ▼ [SNI Tunnel Client] ← Wraps traffic in SSL + injects fake SNI │ │ Looks like: HTTPS → microsoft.com ✓ ▼ [ISP Firewall] ← Passes through — sees only valid HTTPS │ ▼ [VPS Server] ← Decrypts TLS, recovers OpenVPN traffic │ ▼ [OpenVPN Server] ← Receives native OpenVPN traffic │ ▼ Internet The core trick is SNI injection: the tunnel client inserts a trusted domain name (e.g. microsoft.com) into the TLS handshake. The ISP sees what appears to be a standard HTTPS connection and allows it through. The VPS server on the other end strips the SSL wrapper and forwards the real OpenVPN packets to the OpenVPN server.
