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?
tun0 goes away when I am disconnected, so I don’t think anything is keeping it open. I noticed that connections in Proton VPN were set to UDP, so I changed this to TCP and this seems to have worked. Will still want to do more testing to be sure.
I don’t seem to have v3 installed, by the way. The old GUI tool seems to have been uninstalled when upgrading, and the CLI tool I unisntalled myself.
