When using ichat (aim) and talking to another pc or mac user using either the latest ichat version or the latest aim version, whenever we try to connect to do a video chat, I keep getting an error: "Video chat could not be established because you did not respond". This happens even though I click "accept" to the invitation. I have turned off the os x firewall, placed necessary ports in my port forwarding, and have also place the iMac in the dmz zone of the router. I am also updated to the latest os x version. I have tried 3 different routers (2 netgears, 1 linksys-all updated with latest firmware) and all 3 for some reason will not allow ichat video to work. However if I take the router out of the mix, and use a direct connection to my dsl modem, it works. However, this is not a viable option for me as I need the router in place. I have been following other threads here about this problem, but none give a definitive answer or fix to the problem. Any one else having this issue still?
