How to Fix WebRTC VPN IP Leaks

We recently learned that Windows VPN users that rely on Google Chrome and Firefox could be in danger of having their IP address revealed.  Regardless of whether or not you’re connected to a VPN server.  The WebRTC vulnerability allows sites to log your VPN IP address along with your real IP address.

Mac and Linux users are not impacted by the WebRTC security flaw.  It only applies to Windows users running Firefox and Chrome.  Luckily there are already fixes out for both web browsers.  Here’s a quick guide to fixing the WebRTC vulnerability so you can avoid any future IP leaks while connected to VPN.

WebRTC IP Leak Fix in Firefox

Firefox users have two choices to take care of the IP leak issue.  The first is to install the NoScript addon.  If you’d rather not install the addon you can also make a manual change in the web browser.  To do so type “about:config” into the address bar and press enter.  Next click on the “I’ll be careful, I promise” button.  From there you can fix the problem by double clicking the “media.peerconnection.enabled” entry. That will set it to false.  You are now protected from the WebRTC security flaw.
