WebRTC Leaks Your Real Local Network IP in China: Why You're Still Dumbed Down Even with a Proxy
With the proxy on, why is your real IP still exposed? A technical deep dive into how WebRTC LAN broadcasts leak through, plus a hands-on configuration tutorial to completely disable WebRTC leaks in one click.
1. The Blind Spot Proxy Tools Can't Cover: WebRTC
WebRTC is an underlying standard browsers use for real-time audio and video communication. It has the special ability to bypass normal system proxy settings, send STUN probes directly to the local router, and broadcast your real local network and public IP!
2. Completely Plug the WebRTC Leak
1. Visit browserleaks.com/webrtc to test whether your browser is leaking your local public IP;
2. Install the WebRTC Control extension from the Chrome Web Store;
3. Switch the extension icon to blue (Disable WebRTC completely);
4. Test again and make sure all IP fields display as Disabled or N/A, completely cutting off the channel through which Cloudflare can see through you.
