Does anyone know the best way to route traffic from transmission through Mullvad?
I have transmissionset up on my plex server which I control using tranmission remote and want to download my Linux ISOs with privacy.
I have downloaded the wireguard config and can connect to it using wg-quick, but I don’t want all traffic going through it, only transmission.
You don’t, Transmission does not have proxy support. It was intentionally removed a while back & currently the devs have no plans to re-implement it e.g. https://github.com/transmission/transmission/issues/1375
Just use a VPN connection like others said.
