Screens, how to set up port forwarding?

[anon(9758025)]

Hey so I'm about to leave for school and I'm gonna take my Mac with me but not my PC but I wanna be able to connect to it while I'm away and heard of the Screens app and looks beautiful but I am not sure how to set up port forwarding for a NetGear router. What's the easiest way to do this? Also why does this Application lag when I try to use it on my home network the one that the pc and Mac are connected to?
