Mullvad was set to use wireguard. qbittorrent set to use only the mullvad adapter. qbittorrent log showed that it's listening to that adapters ip but found that external ip was mine (upnp was turned off). Then I checked with https://ipleak.net/ https://ipleak.net/ torrent address detector. and it also showed my real ip.
