NAT2 to NAT3 PS3 I’ve Tried Everything?


I’ve been trying for a week now to change my settings to achieve NAT2.

Right now I have a WRT54G2 (v1) and I have these ports forwarded

TCP: 80, 443, 5223, 10070-10080

UDP: 3478, 3479, 3658, 10070

I have a static IP set to all the ports that mirrors the IP on my PS3. (

I also have the DMZ on my router set to the IP on my PS3.

I have UNUP enabled on my router but disables on my PS3. But I have tried all possible configurations with that.

What do I do?

    Having a closed or limited NAT on your gaming console will cause a variety of issues. The PS3 offers Type 3, Type 2 and Type 1 NAT results. These break down as follows:

    Type 1 – Connected directly to the internet (no router/firewall). Should have no issues.

    Type 2 – Connected through a router properly. Should have no issues.

    Type 3 – Connected through a router without open ports or DMZ setup for PS3. Everything should function properly, but you may have connection, voice chat or other issues.

    If you have not adjusted your settings on your PS3 or router, chances are you have a Type 3 NAT and probably never knew it. With a few simple changes you too can have a Type 2 NAT.

    Head over to Network settings from the XMB! Once there choose the Internet Connection Test item.

    In order to open up your NAT on your PS3 you will need to make an adjustment on your PS3 and on your router. First you will want to set up your PS3 for a static IP address. This means turning off DHCP and assigning your PS3 a single, static IP address. Before you start this process head over to the network tab on the XMB and choose “Internet Connection Status.” From here note your current IP address, your subnet mask, your default router and primary and secondary DNS settings. Write these down, you will need them in the following steps.

    To do this, visit the Internet Connection Settings tab on the XMB.

    From here most of the settings can simply be passed through with default settings. There are two areas, however, that you have to change. The first is choosing a Custom address setting (instead of Easy).

    From here, you will want to choose Manual IP Address Setting:

    Remember the settings you wrote down from your status page? You will need them here. You will have to enter in the static IP Address you want to assign to your PS3, the Subnet Mask (which is usually, the default router (the IP address of your router, most often or, and the Primary and Secondary DNS settings. You will have to input all of these numbers. This is made much easier with a DVD Remote or keyboard.

    Please NOTE – You will want to set the last number of your IP address high enough that other wireless or wired items on your network will not be assigned the same number through DHCP. While DHCP had chosen.3 as an IP address for my PS3 initially, I bumped it up to.23 because I have less than 23 items in my network. If you do not have DHCP enabled on your router, you do not need to worry about this and can simply choose an IP address that does not conflict with your other devices and which is available through your router.

    Once you have all of the settings input, press X to save them. Your settings will change and the PS3 will offer to perform an Internet Connection Test for you. If you let it do the test now chances are you will still get a Type 3 NAT connection. Don’t fret little bear, we still have one more step.

    In addition to making the necessary changes on your PS3, you will also have to open up some ports on your router. The ports you need to open are:

    Go to your default routers setting, By typing in your Routers IP in URL Box – linksys’s default is and Username is blank, Password is Admin

    Open these ports: TCP: 80, 443, 5223

    UDP: 5223, 3478, 3479, 3658

    Depending on what type of router you have, your settings page may look different. In order to obtain an open or Type 2 NAT, you will need to open those ports listed above.

    You can see in my screen capture that my PS3 is listed with its static IP address that I set above (.23) and that all of the necessary ports are forwarded to that IP address. The X listed items above (.24) are for my Xbox 360 so you don’t have to worry about those.

    Once you have forwarded these ports and saved your settings its a good idea to unplug and plug back in your router. This will refresh everything on your network connected to your router. Once done head back to your PS3 and perform an Internet Connection Test.

    Turning off Media Sharing Improves connectivity so turn that off, unless you really use it.

    If you still don’t get NAT 2, You’ll need to Bridge your modem with your router, contact your ISP, and Router manufacturer if needed.
