Leaks occur when:

  • You still use ISP DNS
    • Change to VPN DNS
  • WebRTC is enabled in your browser
    • Disable it
  • VPN disconnects and by default there is no 'kill switch'
    • Use ufw for example and set rules so traffic can only go over tun0

https://ipleak.net can help you test for leaks.

Edit:
btw VPN specific applications like the one for PIA do what I listed above, they just don't require you to know how.

    I can confirm that PIA only uses basic networking commands to perform it's functionality. I tinkered with it to get it running on Solus. It's like Harvey said, it just strings together a series of already supported events. The only reason it won't run on Solus is it uses the old net-tools commands (which aren't on Solus).

    Harvey Would you mind explaining how to go about doing what you suggest in your three points? A bit over my head. Thanks! :-)

        Unfortunately. I have committed to 3 years of VPN service with NordVPN. Wasn't aware ahead of time, that it did not have a native app that would wok on Solus. Buyer beware.

          NordVPN does not work as it should on Linux.
          When you connect to a server from them, mysteriously they get you an IP that does not match their server.
          I got in touch with the support, but they are not worried about solving this.
          I simply canceled my contract with NordVPN and later contracted with ProtonVPN. 😁

            Even without the native VPN app, I am satisfied with the NordVPN service. They don't keep logs, and their server info checks out. All that matters to me.

              elfprince I figure if you like it and can live without a component, and it functions effectively, then it's good.

                WebRTC:

                • https://ipleak.net has instructions for disabling WebRTC for your browser at the bottom of the page, alternatively you can disable it from within Ublock Origin extension settings if you use it.

                Using UFW as a firewall 'kill switch':

                    [unknown] What I mean is that Josh gave the link to the issue that was open on the dev tracker for this problem. So you can just click the link to see the status of this issue - which is what you asked for according to my understanding:

                    What happened to the fact that the original poster + me still can't solve the password pop up? Any ideas?

                    [unknown] heum... issues are raised to report problems so they can be tracked and addressed. This is exactly what has been done in this particual case.
                    So if you want to know the status of this particular problem you have to check the issue. As long as it's not closed, it means the problem is not solved.

                    Harvey Thank you very much for your help. I checked and there is no WebRTC leaks nor any DNS leaks. The report shows my NordVPN server address only.
                    I run Solus exclusively. 😁

                      But each time the computer starts, or gets out of sleep, you have a popup saying that you must enter your NordVPN password in order the VPN to run, right ?

                        Bouquins To start the computer (when powering on), yes. I need to login and if I wish, turn on the VPN via the NM. I didn't check the sleep scenario yet.

                            Here is a picture. It is getting more and more ennoying.

                              EDIT:
                              store the password only for this user does not work. store the password for all users work as expected.
