I have just purchased a copy of apple remote desktop version 3 as I am going away to university week after next and need to be able to access my home computer to help my parents with any problems that they have. The problem is, I can access their computer (intel imac) from my laptop (mbp) while on my home network but when I go to my aunts house to try and connect it doesn't work. I know that I have to use the network address of the internet to login but that doesn't seem to work either. My public internet IP is: 83.xx.xx.xxx and then the imac is connected to a router with ip 192.168.1.71 . Can anyone please tell me what to type into remote desktop to connect to this computer. Many thanks.
