Mango V2 wireguard WebRTC leak


I’m using the Mango V2 routeur with a Wireguard ProtonVPN account and Adblocker.

When I test on, the Webrtc shows my internal address.

Is there a way to fix that leak?



Have you tried the fix on

What are WebRTC leaks?

WebRTC implement STUN (Session Traversal Utilities for Nat), a protocol that allows to discover the public IP address. To disable it:

  • Mozilla Firefox: Type "about:config” in the address bar. Scroll down to “media.peerconnection.enabled”, double click to set it to false.
  • Google Chrome: Install Google official extension WebRTC Network Limiter.
  • Opera: Type “about:config” in the address bar or go to “Settings”. Select “Show advanced settings” and click on “Privacy & security”. At “WebRTC” mark select “Disable non-proxied UDP”.
