Hello,
I’m not exactly beginner but only plain user. Since I moved and bought MikroTik several years ago torrents are not uploading at all. Till recently it was not a problem to me. I will appreciate if someone can guide me how to set all correctly. Below are all information I think you need to help guide me to right direction:
Torrent client: qBittorrent v4.1.7. UPnP / NAT-PMP is activated and port is setup to 6666.
Router: MikroTik RB951G-2HnD. I see connection exists there:
DSL modem: ZXHN H168N. UPnP activated as well.

I’m open to all suggestion, just don’t know where to start at all 
Any help appreciatted Thanks!
