My first question is,why would anyone ever want to put a device into DMZ,this opens all your ports and leaves you wide open,like a deer in the headlights..
UPNP should work just fine if you have a decent router or just forward the ports that are needed,as far as DMZ that is reckless and a lazy way out and leaves you vulnerable.
So what should i do.Actually i dont know how to solve the error
my ps3 shows the internet connection as succeeded but the psn connection as failed
i'm really frustrated and want an answer to play online games
THE ERROR THAT I GET is 80710b23
