Block the IP leaks from Opera's VPN

We have recently announced that Opera has released a new browser version of its browser that supports Virtual Private Network (VPN) connections for free. keyboard lock

The new version of Opera protects the privacy of the end user and of course too many were the ones who started using it.

The browser VPN client is free of charge as described above, does not impose restrictions on bandwidth or user data, and there is no reason not to use it unless you already use another VPN.

But it would be good not to stay in what the company says. We need to make sure that there are no leaks of information on remote servers from the VPN application.

If you enable VPN in the Opera and check for leakage in IP addresses, you will notice the following:

The common IP controls αποκαλύπτουν μόνο τη διεύθυνση IP του VPN, αλλά δεν είναι η "" IP του υπολογιστή.
A check with WebRTC Leak service reveals the local and remote IP address of the computer.

To be fair this does not only happen in the Opera web browser, as most modern probrowsers support WebRTC and through the feature they leak the IP address even if there is a VPN enabled on the device.

Some browsers such as Firefox allow you to disable WebRTC completely, while others do not offer this option .

Knowing that WebRTC can be used on websites to identify you, even using a VPN or a proxy server, you might want to disable the feature, especially if you are not using it.

Opera browser does not have built-in options to disable WebRTC, but you can install one που χειρίζεται τις διαρροές WebRTC στο πρόγραμμα περιήγησης και βελτιώνει την της ιδιωτικής σας ζωής, ενώ χρησιμοποιείτε το VPN του Opera ή κάποιο άλλο σύστημα VPN.

Download and install the WebRTC Leak Prevent extension in the Opera browser. You will notice that it will directly prevent access to your local IP address on your computer, but the public IP address of the device will still be visible from Opera's WebRTC application.

Let's see what we can do: Open the extension settings from:

opera: // extensions /

In the list of installed extensions you find if you go to the above address, select options in the WebRTC Leak Prevent extension and in the new window that opens, click the Prevent WebRTC box from using non-proxied UDP.

In the top drop down that says IP handling policy: select "Disable non-proxied UDP (force proxy)".

If you fell a lot look at the picture below:fix opera vpn

 

If you now run a new test to find a WebRTC leak, you will see that it is no longer there. Opera will not show your local or public IP address after installing the extension and the above settings.
