This WEB site shows how to configure PlayStation NAT settings
http://manuals.playstation.net/document/en/ps3/current/settings/connecttest.html

Basically what happend is NAT closed instead of being open NAT. You have to log in to the router ip address in your web browser and set it to open nat. You get your router ip address by going to the command prompt and typing ipconfig. You can google this procedure or consult Netgear as they can walk you through it easily. Youtube has videos on how to open Nat on many different brand of routers. Now you know the problem and what the answer is please rate and comment!!! Thanks.

You are trying to open the NAT on the router for X-box.
For this you will need to reduce the MTU settings on the router to 1365.
You will also need to trigger some ports on the router.
For this you will need to open the router set up page.
Router set up page is the page where you can change the settings of the router

This router does not have the typical "strict or open" NAT types. Looking at the manual, it looks like what you want is NAT enabled and SUA only enabled.

Log into router
go to the NAT tab
Enable NAT
Enable SUA only
Apply the change.

First make sure your security type on the router is WEP-Personal. You may need to get the port range for that game or manufacturer. Then enter them in to the gaming tab. This will keep ports open all the time. NAT 2 is acceptable but you want NAT 1. Some internet connections cannot get NAT1.reply if you need further assistance

You need to open all the ports for the xbox live. The NAT of that router model cannot be configured to open. Its just a simple NAT for internet connection.

Look through the menu's on the router for UPNP. Turn it on. Then turn it on on the XBOX. UPNP is Universal Plugand play. that should configure the router for you automatically.

These routers have a setting underneath the advanced tab (within advanced setup) called UPNP.....all three of the active tick boxes need a tick in (by default they don't) and this will sort the NAT stuff out.
