Batu69 Posted April 23, 2016 Share Posted April 23, 2016 Opera Software added a virtual private network (VPN) to Opera Developer a couple of days ago to improve user privacy and security while using the web browser. This VPN client is free to use, does not impose restrictions in regards to bandwidth or data to users, and there is little reason not to make use of it unless you are already using a VPN that runs system-wide, or want to watch shows on Netflix. One reason given by Opera Software for adding the VPN is to improve privacy by ensuring anonymity while using the browser. As is the case with any other VPN or proxy solution, it is necessary to make sure that the underlying program does not leak information to remote servers. Opera VPN IP leak If you enable the VPN in Opera and check whether IP addresses leak while it is enabled, you will notice the following: Common IP checks reveal only the IP address of the VPN but not the "real" IP of the computer. A WebRTC leak check reveals the local and remote IP address of the computer. This is not unique to the Opera web browser as most modern browsers support WebRTC and will leak the IP address even if a VPN is used on the device. Some browsers like Firefox allow you to disable WebRTC completely while others don't offer that option. Considering that WebRTC can be used by sites to identify you even if you are using a VPN or proxy, you may want to disable the technology especially if you don't make use of it at all. Opera does not ship with built-in options to disable WebRTC, but you may install a browser extension that handles WebRTC leaks in the browser and improves your privacy while using Opera's built-in VPN or system-wide VPN solutions. Download and install the WebRTC Leak Prevent extension for the Opera web browser. You will notice that it blocks access to the computer's local IP address right away but that the device's public IP address is still leaked by Opera's WebRTC implementation. To plug that leak as well, open the extension's preferences. List all installed extensions by loading opera://extensions/ in the browser's address bar and click on the options button under the WebRTC Leak Prevent listing on the page that opens. Do the following on the page: Check "Prevent WebRTC from using non-proxied UDP". Select "Disable non-proxied UDP (force proxy)" as the new IP handling policy. Rerun the WebRTC leak check afterwards to verify that the leak has been plugged. Opera won't leak your local or public IP address anymore after you install the extension and make the modifications outlined above. It is highly recommended to install and configure the extension if you plan to use Opera's new VPN feature. Additionally, you may want to plug the leak in other browsers you use as well.

steven36 Posted April 23, 2016 Share Posted April 23, 2016 This is the same as the one im using from Google in oprea Quote The default settings of this extension will not prevent leaks if you're using Opera's new bulit-in VPN feature. To prevent leaks, open this extension's settings and set IP handling policy to 'Disable non-proxied UDP (force proxy)' and click apply. https://addons.opera.com/en/extensions/details/webrtc-leak-prevent/?display=en There's option for it in uBlock Origin but i dont really like it because at IP leak site it will show you're VPN IP . , By using these force proxy methods it blocks mask the whole ip were nothing shows up at all Link to comment Share on other sites More sharing options...

november_ra1n Posted April 29, 2016 Share Posted April 29, 2016 Stop Opera’s New VPN from Leaking Your IP Address Last week, Opera added a VPN to the dev version of its browser, which was certainly good news. The bad news is that unlike the more robust VPNs it tries to replace, it leaks data that should be encrypted all over the place, namely your private IP address. Here’s how to fix it. Reader Jeff Baines emailed shortly after our story to let me know that he’d tested Opera’s new VPN, and sure enough, discovered that it does leak your private IP address even when you have the VPN running and you’re connected to one of Opera’s exit servers. You can check for yourself over at Roseler’s WebRTC IP leak tester, which we mentioned the last time we discussed how to check if your VPN is leaking your IP. Sure enough, once the VPN is enabled, you’ll see Opera’s IP address in the browser, but the WebRTC leak test will reveal your actual, ISP-provided IP address. (Seen in the image at the top of this post.) Luckily the solution is just as simple: Install the WebRTC Leak Prevent add-on for Opera. Enable it, restart your browser, and try the test again. Your local IP address is blocked now, but your private, ISP-provided IP is still leaked. To fix that, head into the add-on’s preferences, and click the drop-down at the top and choose “Disable non-proxied UDP (force proxy).” Then check the box that says “Prevent WebRTC from using non-proxied UDP.” Try the test again, and you’ll see now that the leak test won’t report ANY IP addresses from you, since WebRTC is being blocked. The end result is you’ll see something like the screenshot below: This is probably the reason many of you reported that using Opera’s VPN doesn’t get you around content blocks like Netflix’s or Hulu’s. Of course, this isn’t Opera’s fault entirely—most web browsers will leak your private IP via WebRTC when a STUN request is made, including Chrome and Firefox. Either way, the add-on is a simple fix that’ll improve your privacy, and one that—if you’re going to try Opera’s new built-in VPN—you should make sure you do as soon as possible.
