2 PS4's on the same network - can't play online

[bishbashboshdj]

Has anyone else come across this problem?

If both my housemates and my PS4's are online at the same time, either his NAT switches to strict, and that person cannot play online.

I've been looking around, and as far as I can tell there is no fix whatsoever at all, its due to both having a the same public IP and the ports being used for that public IP.

Has anyone else come across this problem?

can't say that i have , why not give both of them static ip's
or at least one of them so that they don't conflict with any other .

I used to have the exact same issue with ps3's if two tried to get online just wouldn't work. It ended being an issue with my router. I think I resolved it by flashing the router to use dd wrt www.dd-wrt.com | Unleash Your Router

Don't really know much about this but could it be the port used for port forwarding. Both consoles will be set to the same by default. One will need changing to a different port number.
Had a similar issue with my synology NAS AND Slingbox player, both had port 5001 by default so neither would connect beyond my home network till I changed one.
