Here is How To Disable WebRTC in Opera to Prevent Leaking Your IP while using the built in VPN

Opera has announced this: "We are currently working hard to implement support for proxying even more of the browser traffic, including WebRTC and plug-ins. Having this functionality built into the browser, instead of as an extension, allows us to catch more situations, such as certificate revocation checks made by the system."
-Source: https://www.opera.com/blogs/news/2016/04/opera-doubling-server-capacity-vpn/

^That means that this tutorial might not be needed in future updates of the Opera browser.

In the meanwhile you can use this tutorial to disable WebRTC in Opera with an extension.
I got the tutorial from: http://www.ghacks.net/2016/04/23/block-opera-vpn-from-leaking-your-ip-address/
But I will simplify it here.

This tutorial is for Windows, I'm not sure about Mac or Linux.

1. (Optional) You can check if Opera leaks your IP here: https://diafygi.github.io/webrtc-ips/

2. Install the "WebRTC Leak Prevent"-add-on: https://addons.opera.com/en/extensions/details/webrtc-leak-prevent/?display=en

3. Open the Opera Menu (top-left corner) and click "Extensions" > "Manage Extensions", or copy/paste "opera://extensions/" in your address bar. Then click "Options" on the "WebRTC Leak Prevent"-extinction.

4. Change the IP Handler Policy to "disable non-proxied UDP (force Proxy)".

5. Select "Prevent WebRTC from using non-proxied UDP"

6. Check if Opera leaks your IP again: https://diafygi.github.io/webrtc-ips/

If you successfully did these steps, your Opera Browser should no longer leak your IP when using the built in VPN. The most important part is changing the IP Handler Policy options to "disable non-proxied UDP (force Proxy)", as that will make sure your IP doesn't leak.

I can confirm that this works. Using Opera Dev 38.0 running Ubuntu 14.4. Steps are exactly the same on my OS.

uBlock origin seems to have an option to stop the leaking as well.

uBlock Origin only has an option to prevent your local IP from leaking, your public IP will still be visible on this test site: https://diafygi.github.io/webrtc-ips/

yourdadsuncle's solution - enabling the "WebRTC Leak Prevent" extension - works for me (using Opera 38.0.2205.0 developer on Windows 10 64-bit)

both Local & Public IP are no longer displayed

thanks

I can also confirm this works on Opera Developer v38.0.2213.0 on a Mac running OS X El Capitan v10.11.5 Beta (15F31a).

digitaman, thanks? for pointing that out

as for why IP is reported, I don't know why...

my IPv4 address leaks as well at http://www.dslreports.com/whatismyip when using Opera developer 39.0.2234.0 Private Window with VPN active, on Windows 7 32-bit system

FYI https://diafygi.github.io/webrtc-ips/ only tests for an IPv6 address, when I am in Opera Private Window with VPN active this website does not display an IPv6 address

For fun, since I was once a programmer, I tested this.
I have tried dev 39 and I followed the instructions. The website listed at git seems to not see my ip address. However, if I type "what is my ip" into google or search bar. Google spits it out. Same IP as Chrome spits out in the same session.
Google knows. But I was never signed in and it was a private window too. Unless it took my address from another query before I turned on private browsing.

...Mistake.. I have to click on the vpn now. Vpn icon when I launch it in settings. Now it does not work at all (extensions removed), but others are noting this too. Websites just do not load and vpn turns orange.

onto Build 2245.

this system Win 10 Pro x64 is now running Build 2245.

unfortunately my IPv4 address remains reported by http://www.dslreports.com/whatismyip when using Opera developer 39.0.2245.0 Private Window with VPN active:

---

My web IP address is: 216.144.. *** GOOD! this is Opera Private Window using USA VPN ***
Request Headers do not reveal another IP
Encrypted websocket reveals your IPv4 address is xx.xx.xx.xx *** BAD! THIS IS MY IP ***
