Need default IP

There are several things you need to configure in order to change your NAT to open. Here's a link to help you out:
http://support.xbox.com/en-us/pages/xbox-live/troubleshoot/connection-issues/nat-type-strict.aspx
It has steps that can help resolve your issue.

First of all I would just like to cover the basics of strict and moderate NAT settings. For those interested, NAT stands for Network Address Translation and is used to prevent problems with information being sent over a shared network.
With the XBOX 360, Microsoft have defined three categories of NAT. These are:

1. Strict
2. Moderate
3. Open

You can see the NAT level for your XBOX Live connection by going into your
1. System blade
2. Network Settings
3. Test Xbox Live Connection


For you question on how to open your NAT setting follow the steps below:


1. Type the IP address of your router in a web browser.
2. It will prompt you for a user name and password once connected
3. After logging in you will have a control panel of setting up different settings in your router.
4. The IP address, and default user name/password are different on every route
Note: 192.168.1.1 is a pretty common address for most routers.
5. Check the manual that came with your router for that info.

I also provided a few links below of password lists of different routers.

I hope this information will be helpful. Thank you for using FixYa!

Your feedback is greatly appreciated.

Your IP address may have changed or ports need to be forwarded in your router. Follow this guide from Microsoft to solve the problem:

I've seen many guides on this subject, here you go =)

Basically you need to connect to your routers IP the same way you would go to any ordinary website, if somebody set up your network for you, for example your dad, you might want to ask him to help you out.

Make sure you also open the ports on your router. IF you have all the appropriate ports open and still have strict NAT, it's more than likely your ISP and you should give them a call.

I’m not going to go into too much detail on what your NAT is or why it should be open, but in short, if your NAT isn’t open, you will have a hard time finding games, and it won’t let you join a friends party half of the time. So lets fix this problem.

1. Go to your computer, and get to Network Connections. To do this, you will click on the start menu, and go to “My Network Places”. Once you get there, click on “view network connections” to the right in the Network tasks box. If your computer is hooked up directly to the router, you will be using the Local Area Network, and if you are wireless, you will be using the Wireless Area Network
2. Right click on your connection, and then go to “Status.” If you are using XP, click the “Support” tab at the top. If you are running Vista, you will need to click the button that says “Details.”
3. After you click on “Details” or “Support”, look for and copy down the Default Gateway, and the Subnet Mask. You will need this later.
4. Close this out, and go to your 360 dashboard. Go to the system blade at the very end of the dashboard, and go to Network settings.
5. Go down to Edit Settings. Change your IP address settings from Automatic to Manual.
6. Depending on what your default gateway was, you may have different settings than mine.
7. For IP Address, enter your default gateway. Instead of one digit for the last number, you will need to change it to something such as 109.
8. Enter the Subnet Mask(default for most networks is 255.255.255.0) and Default Gateway in the boxes, and press OK.
9. Now, run a test for Xbox Live. More than likely, you will end up failing the DNS check. This is alright, because we will take care of this in the next step.
10. Go back to Network Settings, and then change your DNS settings to Manual. For primary DNS server, enter your default gateway.
11. Run another Xbox Live test, and you should pass everything. However, your NAT will probably still be Strict or Moderate. If it is open, then you are done!
12. Go back to your computer, and open up your browser. Type your default gateway into the address bar, and press enter. A username/password box should come up. This site has a pretty complete list of routers and passwords.
    
13. Once in, look for a link titles “Applications and Gaming” or something along the lines of that. Click it, and then find DMZ. Click it.
14. Click the “Enable” radio button, and type in the last(4th) octet of your IP(octet1.octet2.octet3.octet4) Save your settings, and exit.
15. Go back to your 360 dashboard, and run another Xbox Live test. If all went well, you should now have an open NAT! Give yourself a pat on the back, and dance around the room a couple times

Ok kids... all you hve to do is log in to your belkin 54g at http://192.168.2.1

Find out what ip address your xbox is using and then Click on the DMZportion of your settings on the left hand side of the page.

Enter the xbox's ip address and click the enable box.
Click apply.


Your NAT will now be OPEN!

Cheers!

Hi Brengolfter3,

My guess is, the IP to your router is still 192.168.x.x. Only way you are going to be able to get to the router, is to set your machine to a static IP, and then try to get to the router.
This site tells you how set it to static, http://corz.org/comms/hardware/router/static.ip.address.php

The IP you listed is assigned to Easton Utilites, so I have asume it is your internet IP. You might want to check the Xbox troubleshooting for the Xbox, so you don't have to disable your Nat, which is a firewall, by default. Good Luck!

First, why are you connecting to your laptop? Second, reset your modem and router. I doubt you need to open ports that are not normally open...but if you think you need to do more, access the router and open the ports manually.

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!
