I am using ProtonVPN, and have (or so I thought) set up qBittorrent to bind to the network interface that ProtonVPN is using (tun0). The connection symbol turns red if I turn off the VPN, and downloads will stop. However, when checking the torrent address on ipleak.net, it seems that this bind is not working properly - my real IP shows up after I have disconnected my VPN. I thought that there shouldn’t be any connections made when traffic is not via the tun0 interface, so that my real IP should never be known by the detection tool. Am I wrong?
I have not configured the kill switch, but perhaps I should do so?
If I start the client without being connected through the VPN, my IP does not show up. It is only when the VPN connection is disconnected and I transition from one network interface to another. This is also if I have the kill switch enabled, so I imagine that if the connection is lost, I am safe as all internet access would be blocked then. And that it is only if I manually disconnect myself that this happens.
Could this be a Proton VPN issue? I am pretty sure I checked this previously, and didn’t see it before the recent Linux client GUI update, but I am not entirely sure.
I’ve noticed before that a manual disconnect from the VPN will automatically disconnect the kill switch but qbittorrent should still lose connection once its bound to the correct interface
Yeah, that is true - I didn’t formulate that quite well. This also happens to me when the kill switch is enabled, as it is disabled when I disconnect. However, it would not disable itself if I simply lost connection, which is in the case where I most want the leak protection. In the other cases, I could make sure to always quit qBittorrent before disconnecting from the VPN. Not ideal, as it would be easy to make a mistake.
