I dont even know if this is in the right section or not. So my isp is virgin media and i have the superhub modem and im trying to portfoward arma 2, When I add all of the correct ports I go to a port checking website type in port 2302, It says its closed. I have this issue with all of my other ports to. I was just wondering if anyone has the same problem as me and if they know how to fix it.
