How Do I Check My NAT type?

[Average-GamerXX59]

Title
i'm not asking how to fix?
do i have DMZ enabled? yes
do i have upnp enabled? yes
there's plenty of that
but none that just lets me see my current NAT type
is there any free software or small free to play game that shows my NAT type?
i don't wanna download destiny 2 or cod just to check NAT type

It's application specific. There is no universal setting for open or strict nat.

Damn it

See it this way, no need to check it for any game you don't have installed.

Have a read: https://portforward.com/nat-types
That describes what NAT types are commonly defined by applications and how those NAT types map to real-world network topologies. Since you know your own network, you can tell which NAT type your app may report.
Basically use DMZ->go worry-free forever (if you practice some basic security hygiene, that is, a DMZ has, IN THEORY, security implications, although only under circumstances which would bite you sooner or later anyway).

I would not enable that.

If a game does not connect for any reason, read what ports it needs open ingoing.

UPnP exists entirely so that people dont have to fuss around with ports locally

Having the DMZ enabled is neither good/bad might waste some resources on the router but its probably negligible

UPnP is by default a security issue as any application can request any port to be opened without the user's knowledge.
Malware loves UPnP.

If you've got malware on your system uPnP is the least of your problems

Well, if you want one of them, you only "need" one of them.

If you dont want to run a server or play a game that did it wrong, you dont need any of them. Even if you can not open ports manually.
