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?
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.
