Windows 10: understanding IP and NAT firewall

This article says:

Not sure if your wifi router has a NAT firewall enabled? Try connecting two devices to the same wifi network, such as a laptop and smartphone.

Now, on each of them, run a Google search for whats my IP?

If you see the same IP address for both devices, youre probably behind a NAT firewall.
I ran the search, and the addresses were each 38 characters long (including colons). The first 19 characters (including colons) were the same, but the last ones were different.

I've only dealt with ip addresses in format ##.#.#.###. What do my googl results mean?

can't get NAT type 2

I just got a Netgear N600 and I replaced my modem recently.

I've opened up the ports

I've set the static IP on my PS3

I've set the DMZ server

I've opened the NAT filtering on my router and turned off every firewall I could.

-----------

With all that I still have NAT type 3. Is it possible/probable that having my DSL fed through a switch is causing this?

Any other suggestions would be appreciated

 

PS3 Nat Type problem

NAT 2 is just another name for PAT (i think). port address translation, which assigns a port for each connection going out to the internet, so the router knows where to send it back.

Some suggestions: disable any firewall on the laptop
Try forwarding the PSN ports to the laptops IP, Im guessing the PS3 is on a different network than the router? Maybe a little IP diagram to confirm that info.

PSN ports:
TCP: 80, 443, 5223
UDP: 3478-3479, 3658

 

firewall rule to block addresses NOT on an IP list?


I am just starting to learn the Windows Firewall (working on both Windows 7 and 10) and I'm not impressed with the inflexibility of its rules. I would like to know if


1. Is there is a way to do what I want with Windows Firewall?
2. Is there is a third-party firewall that would do it?


What I want to do is create a rule that blocks outgoing connections, for program X, that are to a destination **NOT** in an IP list.


Windows Firewall is not very flexible in how you specify IP list rules. When you give an IP list, your rule will match that list... you can't say "trigger the rule for non-matching IP addresses." Therefore to allow outgoing connections to a list, you have to


1. Change the entire firewall policy to block outgoing connections by default so that you can create an "allow rule" matching your list. This will mess up the rest of your programs.


2. Somehow combine a block rule and allow rule. Create a block rule for most traffic, with the "allow" rule overriding it when appropriate. However, this doesn't appear to be possible in general. It **may** be possible for connections that use IPSec, I'm not sure. And I'm not sure if I can use IPSec in my application.

And is there a third-party firewall that can do it? Most 3rd-party firewalls are LESS sophisticated than Windows Firewall, because the use case they are addressing is providing an interface that doesn't require much comprehension. I need one that's actually MORE sophisticated than Windows Firewall.
