[ask] Mac Internet Sharing and Remote Access (Screen Sharing) Problem

[dzigg]

Hey guys, right now my old macbook with Lion is acting as a Wifi Router with OSX Internet Sharing feature at home.

I can do screen share at home no problem. I used dyndns service to connect to it. Also using remote for transmission and jdownloader flawlessly.

But when I'm at the offce, I can't connect to it.. I'm terrible at networking, but from what I gather, maybe it has got to do with port forwarding not set up correctly?

Can someone help? pls.. thx in adv.
