Yes, Mullvad VPN is a great torrenting VPN. It supports P2P traffic on all of its 750+ servers, allowing you to choose a server close to your location to get the fastest download speeds.
In my tests, I was able to download 20 GB files in 15-20 minutes, which is really fast. Mullvad VPN also worked with the most popular torrenting clients like qBittorrent, uTorrent, Deluge, and Transmission. Plus, Mullvad VPN allows port forwarding, which lets you connect to more peers to get faster download speeds.
Mullvad VPN also has a great feature called Connection Check that lets you test if your torrent client is leaking your IP address, and it protects your data with industry-standard VPN security features like a kill switch, strong encryption, and a strict no-logs policy.
