Favourite FOSS Torrenting Client for Linux that has a VPN killswitch?
I'm a long-time Transmission user but I just learned that VPN killswitches are a thing (how did it take me so long!?). I would like to try another client which has this feature in case I forget to launch my VPN client before opening Transmission. Does anybody have any recommendations? Deluge? QBittorrent? Or any others?
UPDATE:
Thanks for the suggestions everyone! I decided to give qbittorrent a try and have been enjoying it so far.
I followed these steps to bind it to my VPN from on Linux:
Pause torrents
Connect VPN
Open qBittorrent. Go to Preferences, and then Advanced tab
Change network interface to tun0. If unsure, disconnect VPN and restart qBittorrent then repeat step 1 to see which interface appears.
Restart qBittorrent
Test it out on the official kubuntu torrent or your favourite distro from LinuxTracker.org. Turn your VPN on and off while verifying whether it pauses and resumes downloading.
Most can bind it an IP even if they don't bind to an interface. I use rtorrent and airvpn/wireguard. Wireguard uses a static IP address for the client and rtorrent can bind to that IP. If the VPN goes down (which is very rare in my experience) rtorrent stays running but it won't work on any other IP address.
