I use a static IP set via my PC not in the router Home Network tab.
I am trying to set up port forwarding for Modern Warfare on PC. I have been able to do this just fine in the past & have had an open NAT in-game.
I recently factory reset the router as the connection was dropping every day, after the reset there's been no dropouts. Since the reset, I set up port forwarding again just as I have in the past but now the NAT is moderate & when checking the ports on https://www.yougetsignal.com/tools/open-ports/ & https://www.canyouseeme.org/ it returns as either the ports are closed or the connection timed out.
I have tried using the drop down menu to select my device & also specifying a User Defined IP Address but nothing seems to get an Open NAT in-game. In the past when I've had moderate NAT I restart my PC & that would fix it but that's not working now.
