This is a quick guide on how to setup IPFire so that multiple PlayStation 5 consoles can play Call of Duty at the same time with an open NAT connection. Call of Duty on the PlayStation 5 uses UDP port 3074. To get an open NAT connection all you have to do is port forward UDP port 3074 to your PlayStation 5's local IP. However, when you have two (or more) PlayStation 5's and you and someone else wish to play COD together at the same time, you cannot port forward UDP port 3074 to both consoles ( You can create the rule but it wont work ) and play simultaneously with an open NAT. One will work and one won't, or there will be connectivity issues resulting in both unable to play. This is normal port forwarding behavior. If you think about what port forwarding does you will understand why. It is a rule that tells your router to send all incoming external traffic inbound for UDP port 3074 to a single local IP. Incoming external traffic: UDP 3074---> send to ---> 10.0.0.2 Now...

I've been using pfsense for a few years and it has been a good replacement over a traditional router but I've been dissatisfied with its online gaming performance. If I plug my modem directly to my PlayStation 5 and play COD MW2, things are good. If I then use pfsense, even if it is configured to allow an open NAT the gaming experience is like there is some form of delay despite having the same ping. I would describe this as other players seem to be reacting well in advanced and I appear to be out of sync. This is more evident when I watch myself dying in the kill cam and see what the other play saw me do. Either pfsense is bad, I've configured it poorly, it's a hardware issue or a combination of these things.  In any event I decided to give IPFire a go and my COD MW2 experience is like I have my modem plugged directly into my PlayStation 5. Even my PC online browsing is more responsive and things are loading quicker! I therefore recommend using IPFire over pfsense -  h...
