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
