On windows, I used Mullvad VPN and Qbittorrent. The settings suggested by Rodneyck are also what I used for qbittorrent.
And a tip: if you notice qbittorrent is not downloading your torrents but has lots of seeders and your VPN is connected… try restarting qbittorrent (right click the tray icon and quit) and it should start downloading.
