Is it the NAT type?

Eg
3

Me and my friend have been trying to play with each other for 3 days… On Ps4 … Well… It just doesn't work. I can't join him and he can't join me… However, Warframe and Fortnite work without problems… But for example. Minecraft or For Honor doesn't work. He suspects that it depends on his NAT type. Can someone help us? He wants to change his NAT type but doesn't know how. YT tutorials didn't help.

It's not that easy. Many providers do not have their own IPv4 address, but have to share one with several other customers. This means that the NAT type is always type 3.

But there are various services that can be used to deal with this. If you or your friend have a Raspberry Pi, you could use this here: http://www.festeip-kit.de/

Thank you, then we'll try it

But you have to consider that the Raspberry Pi limits the speed due to its low performance. http://www.festeip-kit.de/ says something of 20 Mbit / s.
