I've used NetMeeting through my D-Link DI-524. Some routers specifically feature NetMeeting support, but you may need to access your router admin panel and set that up. If your router does not have that feature, you may need to use the DMZ setting on your router. Since this basically negates the NAT firewall functioning of your router, I would not do this unless you have a software firewall running. I believe you would simply tell your software firewall to allow NetMeeting to communicate.
