Huh this is definitely sounding more complicated than what I know about this topic. You can do port forwarding on any router. You just have to set it to forward the QBT port (7832 By default) to whatever the IP is if your local machine running QBT. I thought I'd read you already did that though so I'm a bit confused.
...I think I have heard of ISPs that block incoming connections by default though now that you mention it so maybe that is what you're referring to? It sounds like you may know more about this than I.
