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?
Like the other comments, I use qbittorrent. I recommend running your VPN with gluetun and routing the traffic from your qbittorrent container through it. If the gluetun container is down, no traffic at all. If it’s up, everything goes through the vpn
