NIC bridging over the internet with Python

FunTunnel.py

Tunnel layer 2 traffic over TCP with a single Python script

Features:

• NIC bridging over the internet
• Single script acts as client or server
• No virtual interface is created client-side
• 100% vanilla Python (no external dependencies)

Please be aware:

1. Traffic is obfuscated using an SSL self-signed cert, so it's possible for the data to be decrypted.
2. Requires root access on both server and client
3. Doesn't work on Windows. Tested on Linux.
4. Future developments may include:
   • Tunnelling over well-formed HTTP / WebSockets
