I'm considering implementing UPnP through JJ2, but I'm not sure how many people this will help who could otherwise not host or join games. So I need people to test out a program called PortForward (not mine, I got it from CodeProject). You may need to enable UPnP on your router--or in my case, disable then enable UPnP.

So basically I need testers with hosting or joining problems to run PortForward and then forward the necessary ports through UPnP. Please include all the steps you had to take, and mention if it doesn't work despite having UPnP already enabled on your router.
