noedit,"Not having to port forward" doesn't mean you can just host a server.Not necessarily.it can use UPnP now, if you don't have that or it's disabled, and you haven't port-forwarded, you're out of luck.
And there's still the possibility of firewalls and other programs interfering.Anyways, ticking/unticking is the same as checking/unchecking the checkbox. So basically turn it off, then turn it back on again. Doubt it will help.
