How to prevent WebRTC IP leaks?

[hamed98]

Hello
I have noticed that my real ip could be leaked by WebRTC protocol.(https://browserleaks.com/webrtc), even my browser is opened behind proxychains. Is there any solution to fix that or block the webrtc protocol in the proxychains settings?

seems unlikely. proxychains only sees either a connection attempt, or a DNS resolve attempt. even if we would intercept writes to the TCP socket (with the intention of filtering out WebRTC related stuff), this would only work for plaintext HTTP sites - and these days 95% of pages use HTTPS. implementing this only for the few sites that still use plain HTTP seems like a waste of time. a better solution is to run a MITM proxy like owasp whose certificate you can install in the browser and implement the filtering there. or you just set your browser to not do it - like described in your link, or use a privacy-respecting browser like palemoon.
