I've never done anything like this, but here is the situation:
I'm using a remote desktop application for my android phone called
Xtralogic and it works fine, but only on WiFi. When connected to WiFi on my phone, the app can communicate flawlessly with my PC and everything works fine
What I'm trying to do:
I want to be able to connect over 3G (WAN), but there are some security risks, so I need to do port forwarding or something like that?
The guide is here (under Step 4) and I can't understand any of the terminology at all. I would Google this, but I have no idea where to start and what is what.
My Router Model:
2701HG-B 2Wire
Any help would be greatly appreciated
