How to troubleshoot NAT problems


How to Fix - Error: Your NAT type is set to strict (or moderate)

When you run the Xbox LIVE Connection Test, you receive the following error message:
Your NAT type is Strict (or Moderate). People on networks with this NAT type may not be able to join certain games or hear other people while playing online.
After testing your Xbox LIVE connection, a NAT warning appears as a yellow triangle:


Solution One: Restart your network equipment

  1. Turn off your Xbox 360 console and network hardware (for example, your modem and router).
  2. Wait 30 seconds.
  3. Turn on your modem and wait for it to come back online (approximately one minute).
  4. Turn on the next piece of hardware (for example, a router), and wait another minute.
  5. Repeat step 4 for every additional piece of network hardware.
  6. Turn on your console, go to My Xbox, and then select System Settings.
  7. Select Network Settings.
  8. Select Test Xbox LIVE Connection.
    If you still receive a NAT warning, please try the next solution.


Solution Two: Turn on UPnP on your network hardware


Universal Plug and Play (UPnP) is a standard that helps routers communicate effectively. If your router or gateway supports UPnP, make sure this setting is turned on.

Please refer to your hardware documentation for help turning on UPnP. Most hardware manufacturers have Web sites that include support information.

If you change the UPnP setting on your network hardware, restart your hardware and test your Xbox LIVE connection.

If you still receive a NAT warning, please try the next solution.


Solution Three: Simplify your setup


Your router or gateway might be having problems sharing an Internet connection. To see whether this is true, try simplifying your setup.

  1. If you have a wired connection: Temporarily unplug everything from your router, except the cable to your modem and the cable to your Xbox 360 console.
    If you have a wireless connection: Temporarily turn off everything that’s connected to your wireless network except your Xbox 360 console.
  2. Test your Xbox LIVE connection (on your console, go to My Xbox, select System Settings, select Network Settings, and then select Test Xbox LIVE Connection).

If you do not receive a NAT warning after simplifying your setup, it suggests that the router is having problems handling multiple connections. To try to fix the problem, please go to the next solution.


Solution 4: Open network ports


Your network hardware or firewall might be blocking communication with the Xbox LIVE servers.

If you’re connected to a network through your workplace or a college, ask the network administrator to open the following ports:
TCP 80
UDP 88
UDP 3074
TCP 3074
UDP 53
TCP 53

If youre not connected to a workplace or college network, you need to open network ports on your network hardware. Opening ports can be a little challenging, but the following information will get you started.

Part 1: Switch to manual IP settings

Before opening ports on your network hardware, we need to get the IP settings from your computer and then use those IP settings on your Xbox 360 console. To get your computers IP settings
  1. On your computer, click Start, type cmd, and then press ENTER.

Note If youre using Windows XP, click Start, click Run, type cmd, and then press ENTER.

  1. At the prompt, type ipconfig, and then press ENTER.
  2. Find your network connection (for example, look for something called “Local Area Connection” or “Wireless Network Connection”). Write down the numbers for the following items:
    IPv4 address (or IP address)
    Subnet mask
    Default gateway

  1. Make up a unique IP address for your Xbox 360 console and write it down. For example, add 10 to the last number of your computers default gateway address. (For example, if your computers address is, use for your consoles IP address.)
    Note Each IP address on your network must be unique.

Now lets set your consoles IP settings.
To set your Xbox 360 consoles IP settings

  1. On your console, go to My Xbox, and then select System Settings.
  2. Select Network Settings, and then select Configure Network.
  3. On the Basic Settings tab, select IP Settings.
  4. Select Manual.
  5. Select IP Address.
  6. Enter the unique IP address that you made up, and then select Done.
  7. Select Subnet Mask, enter your computers subnet mask, and then select Done.
  8. Select Gateway, enter your computers default gateway, and then select Done.
  9. Select Done.
  10. Press B on your controller and then test your connection again.


Part 2: Open ports on your router or gateway


Now lets open ports on your router or gateway, so that your network hardware can communicate with the Xbox LIVE servers (this is also called “port forwarding”).
To open ports on your router or gateway

  1. Start your Web browser.

  1. In the Address bar, type the default IP address for your router or gateway, and then press ENTER.

Here are the default IP addresses for a few router or gateway manufacturers.

Default IP addresses:

Netgear or

If your manufacturer is not listed above, refer to your documentation or your hardware manufacturer’s Web site for help finding the default IP address.

  1. Type your user name and password (for your router or gateway), and then click OK.

Note: If you do not know the default user name and password, refer to your hardware manufacturers documentation.

  1. Once you are logged in, you should see your router or gateway’s configuration page.
  2. Open the following ports:
    Port 88 (UDP)
    Port 3074 (UDP and TCP)
    Port 53 (UDP and TCP)
    Port 80 (TCP)

Some resources that might help you open ports on your router is are: - Port Forwarding Guides Listed by Manufacturer and Model. - Port Forwarding Guides for Xbox Live 360

If your router is not listed on the Port Forward Web site, contact your Internet service provider or router manufacturer for help with opening network ports.

nice , thanks :smile:

do you know how to keep open NAT for 2 xboxs on one router. One xbox is wifi and the other is a wired connection.

Wow nice tutorial i like the effort you put into it

Nice one

Or just see Halo Reach’s Menu

What do you mean?

As far as i know it shouldn’t matter how many xbox’s you have on the router as long as you’ve done all the steps above, If its still not working i don’t know? Maybe you’re internet can handle two xbox’s at the same time??

Mine Has No Problem For Me But,When I Do This Will Probably Help.

Nice troubleshooting post. My only question is would ports have ANYTHING to do with NAT? I always thought/was taught that they are 2 different things.

Forwarding Ports allows incoming connections

for example. it allows you to download things faster from torrents

or to make a connection to another computer

or in this case make connections from xbox’s to xbox’s.

Thanks Cheytac

Thanks!!!1 I just got a strict NAT like 5 minutes ago xD

  • Thanks for you good sir :stuck_out_tongue:

Reapect…that one word is what this tutorial is described from myself, you have researched this and got some good resources then constructed it in a good format which is helpful, Respect

well its only because i have a linksys wifi router, and the IP adresses for the 2 xbox’s are different, i can only port foward so many xbox’s with the different ip’s at the end, i agree tho im pretty sure it works my roomate says he has no troubles logging on to XBL
