Setting up DMZ on pfsense

So PfSense and a PS4 don't get along very well. I can't port forward because reasons with my ISP. So here is where I am at. I have a unused TP-Link router and a lot of unused RJ-45 ports on my pfsense box. My plan is to make a DMZ network on one of the ports and then use the router as a wireless access point to make a wireless DMZ network. The issue is I don't know how. Can anyone help me?
