I've been reading up on this, using a MBP I've been able to video chat to people who are on the same wireless network as me, but I get a communication error whenever I try to connect to someone else. The other person is on a wired network so I'm assuming it's my end. She's on a MB. My router is a Netgear 54MBPS Wireless ADSL Firewall Router. DG834G v2. I've heard that I need to forward ports or something and I don't know how exactly to do that or what to do? Is there any way to get this fixed?
