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?
That is what the interface bind is supposed to prevent, or at least that is what I thought it was supposed to prevent. To avoid IP leaks in case of a lost VPN connection. I wonder if I've misunderstood it, or misconfigured it or something else.
You’re correct that it’s supposed to prevent leaks. It shouldn’t fall back, though there may be a checkbox for that somewhere in the menu that you have accidentally ticked? I’m not near my computer at the moment, so I can’t just go digging in my own menus to verify.
I've tried staring with all my might at the different options in the hopes I might identify something. I did turn off the features suggested above in the comment field, but have still been unable to solve it.
I don't understand why that guy suggested turning off DHT and Local Peer Discovery. It shouldn't matter...If you have the client bound to the VPN interface, then that should be that.
