I done this, and opened all the ports and that, but apparently my NAT is still strict.
I think if your XBOX is on the DMZ doing so should be fine. If it's not on your routers DMZ I think you have to forward the correct ports (I can't remember the correct ones) to the IP of your XBOX.
Oh this from MS (

If there is a firewall or a router between the Xbox console and the networking hardware, and if the Xbox LIVE test reports an NAT problem, you may have to make configuration changes to enable communication on the specific network ports that are required by Xbox LIVE. This reconfiguration is known as "port forwarding." If you use an Xbox LIVE-compatible device or a Windows Vista-compatible device that has the correct firmware installed, you should not have to make these changes.
For more information about how to determine whether your networking hardware is compatible with Xbox LIVE, click the following article number to view the article in the Microsoft Knowledge Base:
944293 How to find out if your networking hardware is compatible with the Xbox LIVE Service
If your device is not on the compatible list, and if you experience the symptoms that are described in the "Introduction" section, you can try to open the following ports:
TCP 80
UDP 88
UDP 3074
TCP 3074
UDP 53
TCP 53
For information about how to configure port settings on a firewall, on a router, or on a gateway, please see the documentation that was included with that device, or contact your network administrator or local technical support for help.
