I've set up Remote Management on my iMac, and it works fully on LAN. However,
I would like to be able to remotely manage my iMac over the internet. To do this, I've port forwarded the ports needed for remote desktop (5900), and remote management (3283). I've set up a domain on dlinkddns.com that automatically tracks my dynamic IP. Screen sharing over the internet works, but remote management does not. Is there any obvious reason for this?
Below are the two listings of the same iMac, one is over LAN (hostname Alexanders-iMac.local), and the other is over internet (xyz.dlinkddns.com). Notice the difference in "current status", and the lack of version number.
