In my house I have 2 playstations. My wife and I both play together. On all sort of games but mostly on call of duty. Recently we have been playing Black Ops 3 and have been having problems. We have problems on most games but not as bad as with BO3. The nat type will change from open to strict on hers then on mine from moderate to strict. I'm thinking the problem is 2 playstations trying to use the same ports on the same network so I thought of portforwarding but you can't portforward the same ports to 2 different IP's.

So 1, would it work if I DMZ 1 IP, then portforward the other? And 2, if not can anybody help me solve this issue

To answer your question - using both port forwarding and DMZ would not help your situation. Placing a host in the DMZ means that any ports that aren't handled by port forwarding are instead routed to your DMZ host. As such, port forwarding would take priority, and still only work with one of your machines.

Is this related to your issue? If so, it looks like there is no way to currently do this properly, but some information from this thread may be useful to you.

As @LMFAO_A_JOKE has pointed out and extracted from this thread, the issue is likely due to having the same public IP address being presented to the game server by two different consoles. This has to be handled by the game server in a way that will allow both machines to co-operate, and has nothing to do with what ports are forwarded or opened correctly on your side. As such, the only current way to rectify this would be to have another public IP address, which is not easily possible when you have only one WAN line available.

Note - it's not impossible as typically you could use VPN tunneling or a proxy to present an IP address from a different location, however, how viable this would be with Playstation hardware and trying to get a low latency gaming experience, I don't know.
