Over the past week, I have uploaded over 500 Gigs in total, most of the torrents being only 10-20 Gb big

And those torrents are to this day using the full speed of my internet (that being merely 20 Mbits

So its not really about the speed, but those torrents are not that popular to use my full speed for over a week, therefore I figure there must be a leech (or a lot) wasting my UL from people really trying to get the files

So, how do it block that? I am using download station from my Synology Nas, because I have no way of running qbittorrent-nox
