This may not be possible, I know.
A free VPN has it’s uses. Torrenting isn’t one of them.
Proton VPN.
Free unlimited vpn. It’s becoming a really good company for opensource and privacy related communities.
I use the free VPN all the time.
This seems like a good idea, but the Tor Project website advises against it:
“Don’t torrent over Tor - Torrent file-sharing applications have been observed to ignore proxy settings and make direct connections even when they are told to use Tor. Even if your torrent application connects only through Tor, you will often send out your real IP address in the tracker GET request, because that’s how torrents work. Not only do you deanonymize your torrent traffic and your other simultaneous Tor web traffic this way, you also slow down the entire Tor network for everyone else.”

You can’t use Proton free with P2P…
