Nat / strict

Hi my problem is that when i test my xbox live connection, the NAT comes up as strict. i have contacted my service provider [ 3 broadband - USB modem ] they said there is no firewall from them and that they cannot open the ports suggested by xbox technical support! Neither technical suppports have been very helpfull! I have tried myself to open these ports but am not sure if i have done it correctly. The worst thing is that on Saturday and Sunday the NAT was open and i experienced no gaming problems but then yesterday it came back up as strict. Im connecting my xbox 360 to my laptop via an ethernet cable. Any advice you can give me would be greatly appreciated as i am completely stuck!! Thanks and kind regards

Re: nat / strict

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.

XBOX 360 strict NAT problem

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 cant hear people talking on my ax 180s but my mic doesnt work i have 360 help

ou should check your NAT type [the think that lets you connect, talk, hear, and play with people on Xbox Live]

Go to the Xbox Dashboard, Network Settings and Test Xbox Live Connection.

In the bottom of the tests, it will say your NAT Type

Strict= Bad
Moderate= Sucky
Open= Works Fine

If its Open, then you know thats not the problem.

If its Strict/Moderate, go to More Info and they will tell you more about it and give you a website that will help you out. Source(s): Experience

P.S. [That website that will help you out]

P.S.S. Have you checked the batteries? Sometimes when the battery of a wireless is low, it won't allow you to speak

Nat not open

NAT problems do not always lie within the router hardware, sometimes the firmware may require updating, or the router may not be compatible with the Xbox 360.

I Suggest taking these steps to Try to alleviate your Problem:

1) Power Cycle All the devices Connected to your Network

Follow these steps to power cycle your modem and router:
¤ Disconnect the power supply from the modem, and then disconnect the power supply from the
¤ Press the power button to turn off the Xbox console.
¤ Turn off the computer and any other devices that are part of the network. Leave the devices
unplugged and turned off for at least three minutes.
¤ Turn the modem and router back on by connecting their power supplies. Make sure that all lights
on the modem and router are illuminated according to the manufacturer’s specifications. For more
information, see the documentation that was included with the modem and the router.
¤ Turn on the Xbox console, the computer, and any other devices on the network.

2) Test your Xbox Live connection and Check if the NAT is still showing up as Moderate Or Strict.

3) Navigate to to Check that your Networking Devices are compatible with Xbox Live and also that they have the Most Up-to-date Firmware !

Halo 3

make sure your NAT is open, you can check this by running a connection test on your console. there are 3 types of NAT connection. Open, Moderate & Strict.

Open being the ideal option, strict meaning lots of problems connecting with talking and finding other players on xbox LIVE.

NAT settings can usually be found on your routers setup / settings page (usually ) but some routers may not have setttings for your NAT.

hope that helps
