I did not need port forwarding from my experience (mac).

I did see uploaded data to the peers, not much but some. I assume it would be 0 if i needed port forwarding.

Not really. I upload at 30kbs in Android without port forwarding and at 300kbs with port forwarding. My understanding of it is that it depends on the operating system and wether UPnP works on it. In Android for instance i doubt the engine can trigger the port without manually set your router to forward it

So which port do I need to forward?
