We have recently announced that Opera has released a new browser version of its browser that supports Virtual Private Network (VPN) connections for free.
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 as we mentioned above, imposes no restrictions on users' bandwidth or data, and there's no reason not to. usesunless you are already using another VPN.
But it would be good not to stick to what the company tells us. We should make sure that from the VPN applications there are no leaks of information to remote servers.
If you turn on the VPN in Opera and check if it's there leakage in IP addresses, you will notice the following:
The common IP controls only reveal the VPN IP address, but not the "real" IP of the computer.
A check with WebRTC Leak service reveals the local and remote IP address of the computer.

To be fair this doesn't just happen in the Opera web browser, as most modern programs do browsing υποστηρίζουν το WebRTC και δια μέσω του χαρακτηριστικού διαρρέουν τη διεύθυνση IP, ακόμη και αν υπάρχει κάποιο VPN ενεργοποιημένο στη συσκευή.
Some browsers like Firefox allow you to disable WebRTC altogether 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.
Ο Opera browser δεν έχει ενσωματωμένες επιλογές για να απενεργοποιήσετε το WebRTC, αλλά μπορείτε να εγκαταστήσετε μια επέκταση που χειρίζεται τις διαρροές WebRTC στο πρόγραμμα περιήγησης και βελτιώνει την protection of your privacy while using Opera VPN or another VPN system.
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.
At the top drop down that writes IP handling policy: select "Disable non-proxied UDP (force proxy)".
If you fell a lot look at the picture below:
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.
