How To: A guide on how to open you NAT for XBL.

How to: Opening your NAT for Xbox Live
Guide by: Kakarot

Step 1:
Get your Xbox's IP address.

Step 2:
Go to you internet explorer. Type in your router's IP address. It should be default at 192.168.1.1 or 192.168.2.1. You should then see a box that asks for username and password. If you haven't changed it, both of them will be admin.

Step 3:
You should now be in your router settings. Look for the DMZ tab. Once you find the DMZ tab, click enable and type in the last digits of your Xbox's IP address into the box below. Make sure to save your settings.

Step 4:
Now you will need to find the Port Forwarding tab. For the name use whatever you feel like. I used XBL.
- Put 87 to 89. Choose UDP. Then the last four digits of your Xbox's IP. Click Enable.
- Put 3073 to 3075. Choose TCP. Then the last four digits of your Xbox's IP. Click Enable.
- Put 3073 to 3075. Choose UDP. Then the last four digits of your Xbox's IP. Click Enable.

Save your settings.

Step 5:
Enable UPnP, if you can't find it. Don't worry about it. It's not a must.

Save your settings.

Step 6:
Now log out. Unplug your router and modem.
- Plug router in. Wait 30 seconds.
- Then plug in modem. Wait around 2 minutes.
- Not doing this may cause failure.

Step 7:
Restart your Xbox. Test your connection. Wait a moment for the settings to fall into place. It should say open when the test is done or it will say nothing at all. Meaning it's open.

If none of this works. Repeat step 4 for step 5. But, do it in UPnP. All routers are different. If that doesn't work, you can just try again or do a factory reset. Which is the button in the back, that is really small. You can always buy a router that has gaming enabled on it. Make sure to check the box before purchasing.

This works for me and my friends. I hope it works for you.

If you need help and cannot figure it out. Please don't hesitate to ask for proper direction.

Thanks for reading.

Good Guide. I'll do a list which will link to a ton of guides later on.

Very nicely done!

However... If you set an xbox as a DMZ, the port forwarding is not necessary. DMZ stands for DeMilitarized Zone, which means the xbox will sit "outside" of the firewall and no NAT translations will happen to/from that IP. I've always set my xbox as DMZ and have never port forwarded and I do not have any issues.

Another thing to note is that your Xbox will not ~always~ get the same IP address, unless you set it to static in the Xbox settings, or give it a static DHCP lease in the router. If you go on vacation, for example, and your PC and Xbox are off for more than the DHCP lease time (usually 5 days), there is a possibility that when you come home and turn them both on, their IP's may swap, meaning your PC is now the DMZ and will not be firewalled or NAT translated. This is generally a really BAD thing to do to your computer.

Also, a quick way to get your routers IP address (in case it's not 192.168.1.1 or 192.168.2.1)::

Click START
--IF XP, click RUN and type CMD and hit enter
--IF Win7, type CMD and hit enter
In the new window type "ipconfig /all" without quotes
Your "default gateway" address will be the address of your router.

DMZ doesn't work with all routers. That's why you have to do all the steps.

And, about the vacation and such. I've done that plenty of times. It's never happened. But, I may be lucky.

@HammerTime, thanks, pal.

@MidKnight, you're welcome.

Oh, no worries my friend...

I expected nothing less than complete and utter backlash for trying to HELP and ADD to the information you posted. (that I actually complemented you on, remember?)

And yet people still wonder why the Halo community is dying.

Good guide. Now what if you have a combination modem/router that doesn't allow you to train two IP's with an open nat, essentially leaving you with one open one moderate, that will occaisionally have matchmaking issues. I know one way is to bridge it to another router and then just piggyback them but do you have any other suggestions?

If I understand you correctly, you're trying to connect 2 xboxes and want both of them to have an open NAT.

I've never had to personally do this, but I've heard that if you set one of the xboxes as a DMZ, and port forward (as outlined above) to the second xbox and that may give you the desired result.
