Step 3 : The Default Password is admin

Step 4 : At the top Click Advanced

Step 6 : Enable DMZ

Step 7 : give the IP Address of the Xbox/PS3/Wii in it

Step 8 : Uncheck the option Enable SPI

Step 9 : Click Save Settings

Step 10 : Test the connection

let me know if this works

To reduce the NAT

1 ) Disable the firewall in the router

2) Enable the Playstation in the DMZ

3) Make sure UPnP is Enabled

PS3 and Xbox ( NON BELKIN)

You Will Have to Disable the Firewall In Your modem / Router

And IF it is a router then Open The Ports

• TCP 80
• UDP 88
• UDP 3074
• TCP 3074
• UDP 53
• TCP 53

And also make sure that UPnP is Enabled

If any firewalls were installed on your computer, or any ports we closed, you NAT type may have been change from OPEN to STRICT or MODERATE.

OK NOW THAT CAN ONLY BE CHANGED by the manufacturer i believe , or the internet supplier , because mine ( virgin broadband ) varies sometimes , when i play some games depending it sometimes says strict, open , or moderated so its more likely nothing to do with the settings.

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.

upgrade your router to the latest firmware that can be found here:
http://kbserver.netgear.com/products/WGR614.asp

after upgrading the firmware, press the reset button for 30 seconds, then reconfigure the router. you will need to re-enable upnp if it is disabled, and open up ports UDP 88 UDP 3074 TCP 3074. i would also reserve the ip for the xbox and if all else fails set the xbox as the dmz host.

hope this helps,

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!
