What Is WebRTC?
WebRTC (Web Real-Time Communication) is a browser API used for video calls, voice chat, and peer-to-peer file sharing. It can bypass your VPN tunnel and reveal your real IP address to websites.
Step 1: Install a WebRTC Blocker Extension
Chrome doesn't let you disable WebRTC natively, so you need an extension:
- WebRTC Leak Prevent — lightweight, focused blocker
- uBlock Origin — blocks WebRTC leaks plus ads and trackers
- WebRTC Network Limiter — Google's official extension
Step 2: Configure uBlock Origin (If Installed)
Open uBlock Origin settings → Privacy → check "Prevent WebRTC from leaking local IP addresses."
Step 3: Use NordVPN
NordVPN's browser extension and desktop app include built-in WebRTC leak protection. It blocks WebRTC from revealing your real IP without breaking video calls or other functionality.
Step 4: Test Again
Run our WebRTC Leak Test to confirm Chrome is no longer leaking your IP.
