      then let's see:

      First, create an independent interface for the game machines.
      This can be a physical interface, if you have an empty port on your hardware (NIC), or it can be a separate VLAN (on LAN interface)

      540de5ed-bbd9-4f1f-b532-edbd95f28099-image.png

      Second step, set a fixed IP address on the game machines or you can use dhcp too, if you record the IP addresses of the machines in the dhcp server "static mapping" - in this case run dhcp server on the interface which you created in the first step

      third step: add the default NAT rule of the interface (game interface), so that the interface has an internet connection, so:

      41204bcd-7b7e-4eb0-bcc4-b6ee384e27cf-image.png

      fourth step: create a hybrid outbound NAT mapping containing the IPs of the gaming machines (with / 32 subnets (no / 24!)), so:

      89e1927b-1a1d-4310-aece-9552938f071b-image.png

      step five: turn on UPnP & NAT-PMP for the game interface ONLY to separate game machines from other vulnerable network components

      when you start a game machine (on this separated game interface) you can check the open ports in the menu: Status / UPnP & NAT-PMP

      b35d94a7-3e95-4eb6-87f0-ca40022b9d44-image.png

      As I mentioned on a firewall, UPnP & NAT-PMP is not a really good thing, so you need to separate this intarface.
      if you have any questions, I am at your disposal

      Thank you very much for these instructions. I finally got my gaming VLAN to come up with NAT Type open. ๐Ÿ‘

      I followed the steps exactly and it was perfect except for one thing which messed me up. After the last step, I had to go to Diagnostics > States. I filtered for my Xbox static IP and then I had to Kill the states. Without doing that it kept the old states and kept showing NAT type strict.

      Just wanted to add that in since that could cause headaches for others. By the way, I'm not taking credit for discovering this, I found it in the documentation. I just knew I was missing something!

        you're absolutely right...๐Ÿ‘
        since, I always restart (NGFW) when such a configuration change (greater extent) is made, I forgot to describe it

                Hi,

                With Destiny 2, it won't work, sorry ๐Ÿ˜ž (on the same sub-net)

                    So,
                    If I follow your guide I would still get the warning when playing D2 on the PC? What would I need to adjust in order to get rid of that warning?
                    Thanks,
                    Truckin

                      Hi,

                      It depends on the philosophy of the different game manufacturers...

                      in general it can be said that there is no problem based on Linux (FW), but here and with D2 this has not been solved yet

                      there is an initiative for it, this will perhaps be a result in 2.5:

                        Ah,
                        I see. Well, hopefully, they will provide a resolution.

                            Are you still facing the same issue or you recovered?

                            It's still an issue for myself and playing Destiny 2.

                              @jailbird4 I just play with strict NAT types now. Obviously just a limitation of the software. Software which I didn't pay anything for, so I'm not too worried about it lol

                                  As I did a quick visit the last weekend with our youngest in D2 I can't find any problem even when not having pure NAT. We've played with two PS4s with both NAT Type 2 (not strict/3 but not pure/1 either) without a hitch. Got together, got into PvE/PvP - don't see problems.

                                  Don't forget to upvote ๐Ÿ‘ those who kindly offered their time and brainpower to help you!

                                  If you're interested, I'm available to discuss details of German-speaking paid support (for companies) if needed.
