I thought you were able to from another network that is over the internet.
"Access and control your Mac running Mac OS X Leopard from any other Leopard-based Mac over the Internet right in the new Finder. With .Mac and Back to My Mac, youre always close to your files and applications."
Didn't think you had to be on the same netowork
Yeah, it doesn't work for me, either. Apple claims it now works better in 10.5.1, so I'll give it a try tomorrow when I'm at school. It's a shame, too, as it's a very useful thing to take advantage of, and I wouldn't have to pay monthly for a third party service like GoToMyPC.
Your problems could also be your IT department at work not allowing access through the corporate firewall. I know that I cannot access my home Mac from work because of this.
Maybe this is it.
I can access the work computer from home, but not the home from work. It's a bit of a shame, but I'll live I guess. Kind of defeats the whole thing though.
Maybe my home router has a port closed? Which ports might I need to open? I think it's a bit silly really.
