I will try to set up the DMZ again, or at minimum a static IP for my PS4.Other than that we've had no issues

You can work around this limitation via assigning the machines a static ip (router configuration based off of the machine's nic) and then adding that ip to /etc/hosts on the machines; but this is kind of a pia and fragile
