🛡️ VPN-Hater

🌐 VPN-Hater is an innovative, open-source solution aimed at enhancing network security by blocking VPN connections. Distinguished from traditional inline methods, VPN-Hater is both reliable and cost-effective, ensuring uninterrupted network performance even in high-traffic scenarios.

Environment

• Linux

🚀 Key Features

• 💡 Out-of-Path Method: Guarantees uninterrupted network performance.
• 🔒 Packet Injection: Expertly blocks VPNs by injecting termination packets.
• 🔄 Supports Multiple Protocols: Compatible with PPTP, L2TP, TCP Based VPN(OpenVPN TCP), and non-encrypted OpenVPN UDP.
• 🏎️ High Traffic Handling: Maintains consistent speed under heavy load.
• 💸 Cost-Effective Solution: Minimizes equipment replacement costs.

🛠️ Usage Guide

🌟 Setting Up

1. Network Environment Setup: Configure your network for port mirroring.

   1) Using TAP device to mirror packets

   

   2) Using Internet Router with port mirroring function

   

   3) Using Switch with port mirroring function

   

2. Installation:

   $ git clone https://github.com/bob12vpn/vpn-hater.git
   $ sudo apt install build-essential
   $ sudo apt install libpcap-dev
   $ make -j

   add -j option for compile faster

3. Execution:

   • command

   $ sudo ./vpn-hater <mirror interface> <send interface> [sni list txt]

   • example

   $ sudo ./vpn-hater eth0 wlan0 sni.txt

📡 How It Works

• PPTP & L2TP: Strategy involves injecting termination request packets.
• OpenVPN UDP (Non-Encrypted): Employs explicit-exit-notify packet injection.
• OpenVPN TCP: Utilizes parsed signature & injects FIN/RST packets.
• TCP-Based VPNs: Enhanced blocking via signature parsing.
