router/netmeeting

I want to get netmeeting to work trugh Linksys router, I opened all this ports >> http://support.microsoft.com/default.aspx?scid=kb;en-us;158623 , and nothing, it's not working. When I set my comp. on DMZ, then it works. Same problem with my parents D-Link router. All this ports open and no luck. I wss reading lots of info how to get it working, but is anyone actualy got it working around here??? Pleas share any info you have on that.
Thnaks.

no one did it, ahhhh, sad.
