Hi, I have a problem with my asus RT-N18U and that is that I cant chnage my nat type to either moderate or open, its always on strict. I want to get open nat type on my ps3, ive given it an static ip adress already. I tried opening all ports that were needed for call of duty, I have tried DMZ my whole router and the ps3's ip adress, didnt work. I tried turning off my routers firewall, didnt work... So, I dont really know whats left to try? I hope someone on here can help me out. But there's one thing, on my ps3 when I test my internet connection, it says that uPnP is available, so I guess it isnt using it properly but it's available, can that be the problem?
