      Dear Community,

      Step by step I came closer to tame the monster PS4. Unfortunately, I've been stuck at the last step. The TL;DR is that I cannot get multiple PlayStation 4's to get a NAT Type 2 using the same public IP and using UPnP. Perhaps this is not even possible, so I hoped to get some experiences from fellow pfSense users.

      Let me first describe my network set-up shortly:

      ISP –-- ISP Router (DMZ) ---> pfSense  --- VLAN X ---- Playstation 1/2/3/4

      So there is a router from the ISP, and a router for the network. The pfSense router is set as DMZ from the ISP router.
      All gaming consoles are in a seperate VLAN, but this should not really matter.

      The configuration:
      Services -> UPnP

      • Enabled
      • Allow UPnP Port Mapping Enabled
      • Allow NAT-PMP Port Mapping Enabled
      • External Interface WAN
      • Interfaces (VLAN X selected)
      • Override WAN address: WAN adres of ISP router
      • Default Deny Enabled
      • ACL Entries: lines of:
        allow 1024-65535 172.20.6.x/32 1024-65535

      Something Works! :)
      If I check one PS4 console, test it network settings, it'll say "NAT Type 2". In the UPnP & NAT-PMP status table I'll see:
      Port / Protocol / Internal IP / Int Port / Description
      9308 udp 172.20.6.x 9308 172.20.6.55:9308 to 9308 (UDP)

      So far so good.

      The Problem:
      As soon as I try to use the second, third, whatever x ps4 console and use the same test, it'll show NAT Type 3. When I shortly disconnect the first PS4 and retest, the firstly connected console will have a Type of 2, and a corresponding rule in the UPnP status table.

      As such it appears that the entries get overridden and I can only use one console at a time for these online services.

      Is this a common problem? Are there ways around this issue without needing to have multiple IP's? I'm specifically talking about the NAT Type issue, it is not a problem to let multiple consoles to internet at the same time.

        Hi - Did you ever get this figured out? I am having the same issue. PS4 1 works fine, PS4 2 has issues in online games, specificly COD.
