It is the “Torrent Address detection” magnet link I am using, and it is this that reveals my real IP when the VPN is disabled. The traffic in qBittorrent stops though.
EDIT: And as I mentioned in an earlier post, it works as intended if I open the client when not connected to the VPN. It is just if the client is running while I disconnect that this problem occurs, as far as I can tell.
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.
Thanks - those were both enabled, and I’ve disabled them now. However, this still happens after I’ve done this and restarted the client. I also tried turning off peer exchange that I found together with these options under the Privacy tab, also without solving the issue.
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.
