UPnP works wonders and before I went to University I used it to forward ports for JJ2 without having to make permanent rules in the router webgui. So I can confirm it does work in some situations. Having the support by default should aid a lot of people

It should be noted if anyone is using Internet Connection Sharing in Windows the only way to forward ports is UPnP so this would also benefit ICS users.

And by adding upnp support, Black Ninja will be your best friend for ever and idol you apparently:
