I have used Touchpad Pro from my WiFi network to control my Mac, but what about controlling it remotely when I am not connected to my WiFi network...?
I use ADSL Internet with IP Address: 18.104.22.168
The connection directly goes to my Belkin WiFi Router: 192.168.15.1
I have many computers on the network, and my Mac has the IP: 192.168.15.4
Now, which IP address do I enter in Touchpad Pro...?
