I recently purchased a D-Link DGL 4300 gaming router.  It is wireless, but I have both my PS3 and 360 hooked up wired.  I cannot seem to get the PS3 at Nat 2, and the 360 fails the MTU tests but I can play online with NBS 2K8 so who knows.  I am trying to forward or open ports, but am unsure if i am doing it right.  I have a DSL internet connect with a Speedstream 5200 modem.  Anyone with some advice or a good walkthrough tutorial and I will be forever grateful.  
Thanks,
Mike
