No, if it's not working then you did it wrong.If you'd like to use the UPnP feature (which doesn't require port forwarding), you might need to reboot your router by unplugging it, waiting 10 seconds, and plugging it back in.
I didn't catch you saying clearly that you have been able to host previously.
Alright, i port forwarded and everything but it will not work, is there anything else i can do also?
Is your computer's private IP static?
