Unlock IPv6 Without ISP Support! Easy Proxy & Tunnel Setup Guide for Secure Browsing

I need to set up a home proxy server to connect to websites via IPv6, even though my internet provider only supplies IPv4. My modem doesn’t support IPv6 directly. How can I do this simply and securely?

Simple Explanation of the Solution:
Since your provider only gives you IPv4 and your modem doesn’t support IPv6, you can use a computer as a middleman. By using a free tunneling service (like Hurricane Electric), your computer can get an IPv6 address. Then, you can run a proxy server on that computer to forward your internet traffic from IPv4 to IPv6. This is useful for testing IPv6-compatible websites or accessing resources available only over IPv6.

Step-by-Step Guide:

1. Get IPv6 via a Tunnel:
- Visit tunnelbroker.net and sign up.
- Create a tunnel: enter your IPv4 address (provided by your ISP) and choose the nearest server.
- Copy the setup instructions (commands or script) for your system (Windows, Linux, etc.) and run them on your computer.
- Check if IPv6 works by visiting ipv6-test.com.

2. Set Up a Proxy Server:
- Install Python (a free coding tool) from python.org.
- Use the simple script below to run a proxy on your computer.
- The proxy will listen for requests from your devices (like a phone or another computer) and forward them over IPv6.

3. Connect Your Devices:
- In your device’s network settings, set the proxy to your computer’s IP address and port (e.g., 8080).
- Test the connection by visiting IPv6-enabled websites.

Proxy Server Code (with HTTPS Support and Multiple Sites):

```python

Code: Select all

import socket
import threading
import ssl
import re

# Proxy settings
LOCAL_HOST = '0.0.0.0'  # Listen on all local connections
LOCAL_PORT = 8080       # Proxy port

# List of target servers (domain: IPv6 address, port)
TARGET_SERVERS = {
    "example.com": ("2001:470:1:1::2", 443),    # HTTPS site
    "test-ipv6.com": ("2001:470:1:2::3", 80),   # HTTP site for testing
}

def parse_host(request):
    """Finds the target site from the request"""
    try:
        decoded = request.decode('utf-8', errors='ignore')
        host_match = re.search(r'Host: (.*?)\r\n', decoded)
        if host_match:
            return host_match.group(1).strip()
    except:
        return None
    return None

def handle_client(client_socket):
    """Handles connection from a device"""
    request = client_socket.recv(4096)
    host = parse_host(request)
    
    if not host or host not in TARGET_SERVERS:
        print(f"Unknown site: {host}")
        client_socket.close()
        return

    remote_host, remote_port = TARGET_SERVERS[host]
    is_https = remote_port == 443

    # Connect to the site via IPv6
    remote_socket = socket.socket(socket.AF_INET6, socket.SOCK_STREAM)
    try:
        if is_https:
            context = ssl.create_default_context()
            remote_socket = context.wrap_socket(remote_socket, server_hostname=host)
        
        remote_socket.connect((remote_host, remote_port))
        
        if is_https and b"CONNECT" in request:
            client_socket.send(b"HTTP/1.1 200 Connection Established\r\n\r\n")
            request = client_socket.recv(4096)

        remote_socket.send(request)
        
        while True:
            response = remote_socket.recv(4096)
            if not response:
                break
            client_socket.send(response)
    except Exception as e:
        print(f"Error: {e}")
    finally:
        remote_socket.close()
        client_socket.close()

def start_proxy():
    """Starts the proxy server"""
    server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    server.bind((LOCAL_HOST, LOCAL_PORT))
    server.listen(5)
    print(f"Proxy running on port {LOCAL_PORT}")

    while True:
        client_socket, addr = server.accept()
        print(f"Connection from {addr}")
        thread = threading.Thread(target=handle_client, args=(client_socket,))
        thread.start()

if __name__ == "__main__":
    try:
        start_proxy()
    except KeyboardInterrupt:
        print("Proxy stopped")
        
```
How to Use the Code:
1. Save the code to a file, e.g., `proxy.py`.
2. Update `TARGET_SERVERS`:
- Replace domains (e.g., "example.com") with real ones you want to access.
- Use their IPv6 addresses (find them with `ping -6 domain.com` if you have IPv6).
- Port 443 is for HTTPS, 80 is for HTTP.
3. Run the script:
- Open a terminal, navigate to the file’s folder, and type: `python proxy.py`.
4. Configure your device:
- Set the proxy to your computer’s IP (e.g., 192.168.1.100) and port 8080.
