I dont really need the use of multiple ports simultaneously. Im ashamed to say it, but I do not do that much seeding, I use mostly public websites with public trackers. So its not really for the torrenting aspect I was curious about port forwarding about. As I mentioned in my post, it was when I was trying to see whether I can set up a jellyfin service for people I know to access my music that I found my ports cannot be opened. So it was with regard to that my post was initially about. Anyways, thanks for your input.
Thats really helpful, I think I am going to try this out. The whole VPN and port forwarding feature I was curious about happened because my ISP doesnt allow port forwarding and I was unable to set it up for sharing my jellyfin. I will try to read the link you shared and try what I can do! Thanks a lot!
