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.
Docker with a gluetun container. This container’s only role is to connect to my VPN provider. Any traffic I want through the VPN is set to use that container as its network. If the VPN goes down, gluetun loses connection, any container attached to gluetun can no longer access the internet.
I use a qbittorent docker container for my torrent client but you can attach whatever client you’re comfortable with, as well as any other container you prefer be on a VPN.
While qbittorent has a built in kill switch, this works for everything. No VPN means no connection, period.
