(R6350) Two PS4's on same network

I have 2 PS4's in my house and I need to have an Open NAT Type on both of them in order to play certain games (in this case, it is Call of Duty: Modern Warfare Remastered). One of my PS4's are in DMZ so I have an Open NAT Type on it, but my other one has a moderate NAT Type (Type 2). They are both plugged in through LAN. My router is an AC1750 (shown below). I am new to this whole process so please explain thorughly
