Transmission and torrents

Hello All,
what is the correct setup for using a torrent client ?
I installed transmission with pakfire, and set my Ubuntu Qbittorrent to use the IPFire address as proxy, but it is not working, so I must miss something…
Thanks for reading and commenting!,

I think the transmission addon.
Is a GUI version running on your ipfire.
Not a proxy for your lan network to torrent threw.
Or? https://ipfire:9091
