I'm trying to change my nat type from 3 to either a 2 or 1. Also my UPNP needs to be available.

How to Change Your NAT Type on PS4 and PS3

I take this is your type of network you have. NAT (Network Address Translation) only job is make all the IP's of you LAN to be able to use the one IP From the ISP. For example, you can have 3 Pc's connected to router (192.168.1.1 to 192.168.1.3) with only one connection to ISP, and address like 67.123.43.200 (Address change upon ISP location).
In order to the game communicate between PC ans Internet have to configure Ports to connect to. Thanks to UPNP (Universall Plug and Play) this configuration is made automatically between the PC and the Router and simplifies those configurations.

Things to check:
The router have UPNP and is on.
There's a Firewall interfering with the game.

Hi ..

The PS3 has 3 different NAT types. They are shown below.
Type 1: The PS3 is connected to the Internet without a firewall or router. No NAT issues.Type 2: The PS3 is connected to the Internet through a router which is configured correctly. No NAT issues.Type 3: The PS3 is connected to the Internet through a router that needs configuring.Ideally, you want to have a Type 2 NAT. However, a Type 1 NAT does not affect your game play.


First of all you will have to Disable the firewall in the Router / Modem

If you are using a Router ..

Then

Make sure that UPnP(Universal Plug n Play) is enabled
Enable the IP Address of the PS3 in DMZ

Or Forward the ports

Below are the TCP and UDP ports that need to be forwarded:

TCP: 80, 443, 5223
UDP: 5223, 3478, 3479, 3658

Hope it helps

STEPS TO CHANGE NAT SETTINGS TO "OPEN":

1- Using your Browser, Log on to your router (by normally typing in the 192.168.1.1 address check your router's manual to see what the default gateway address)

2- If you already know how to log in to your router, then skip this step. If you have never logged on to your router then more than likely you still have the default initial log in credentials (username: admin - Password:1234 ..... Again check your router's manual to be sure). The minute you log in you need to change that password immediately, most network-savvy folks know that 90% of the people out there never reset their router's initial password and they can log on and make any changes to suit their needs, including locking you out of your own router.

3- Once you are logged in, you should be able to find two advance settings (One if for NAT - and the other is for Upnp)

4- Let's start with the NAT setting changes, and we will move on the Upnp at the end. I have personally tried the NAT setting changes and it didn't fix anything, I still had a "Strict" NAT setting on my xbox360, Only when I checked for the Upnp "allow authorized incoming traffic" options when the NAT settings on my XBOX finally came back as "Open" and not "Strict". But I will still explain what I did anyways with the NAT table cause I know it may work for some other routers.

5- So what I did with the NAT setting is this. I located the NAT advanced setting on my router, I click on the NAT (Edit List setting) or whichever link/button you have on your router advanced NAT settings to access the table needed to open certain ports (TCP and UDP - 88 & 3074) .

6- You will need to find out what the static/dynamic (preferably Static) IP address you xbox360 has. To do so, go to the Dashboard, go to the Console settings page, and click on the network settings to see the IP address (should be something like 192.168.1.x). You will need that IP address to enter into your NAT table on your router.

7- Once you got your XBOX's IP address enter it in the NAT Port Forwarding table (From - To - IP address: those are the 3 fields you should have on the table if you are using SUA NAT)

8 - In the first line enter 88 under both "From" and To" fields, then enter the IP address of the xbox in the field where you are to enter an IP address. (this is for UDP port)

9 - Repeat the same step for port TCP (which is 3074)

10- If these changes do not help open your NAT settings, then try the Upnp option. Click on your Upnp Advances settings and click on the "Allow Traffic" option, this is mostly secure because you are only accepting the incoming traffic that matches your outgoing traffic.

To reduce the NAT

1 ) Disable the firewall in the router

2) Enable the Playstation in the DMZ

3) Make sure UPnP is Enabled

To reduce the NAT

you need to make sure that when you change it that you apply in your modem setup page that bridge mode is activated so that it turns it into a dumb unit allowing just to pass through the internet stream thus allowing constant nat 2 connection

you're goin to have to call your internet provider about this

I have this router and have just enabled the NAT settings from Strict to Open:-

1. Log into router's IP address (192.168.1.1) and enter password. Select "Advanced Setup".

2. Click on Advanced on left hand menu and select UPnP

3. Check all three boxes in window and click on Apply

4. Close router configuration window and run XBox test again. Worked for me!
