Has anyone had any problems with Apple Remote Desktop? I cannot connect to a specific remote desktop when the Mac is connected through the router. If I connect directly to the modem, everything works fine. I've tried putting the Mac in the DMZ. I've even tried opening ports 3283, 5900, 5988 in the virtual servers and port forwarding (but not at the same time). I'm able to connect to other remote desktops, except this one.
I'm running the latest firmware 3.12NA
Any idea? Thank you in advance.
