www.portforward.com choose your router from there and follow the directions!

Are you trying to connect the Xbox to the wireless network?
If yes then you will need to check the wireless settings of the router.
is there any computer on line using the router ?
on that computer you can open the setup page of the router. check the wireless ettings and the security settings then try to connect to the wireless network on the Xbox.
See if that works.

easy. get the IP addy for your xbox, goto your router set up page and put that IP in the DMZ zone.

Playstation Guides ( PS3 ) to change from NAT3 to NAT2... 
Guide1 or Guide2 or Guide3  

since NAT has to be set on the Linksys...
you will have to use the software provided by linksys, or use a web based interface which connects to the linksys and you can do the respective changes...!!!

The information on page 70 or 71 does not give you the information you need to allow you to play your Game?

I have the same router (WRT300N) and this is what I did. I don't know if it will work for more than one Xbox360.

- Go to the Setting of the router.

- Applications & Gaming

- DMZ 
. Enable the DMZ
. Choice the Mac Adress under the Destination.
. If you don't know the Mac Adress of your Xbox360 click on the tab: DHCP CLIENT TABLE
.Now from there choice your Xbox360 ( the Xbox360 won't have a Client Name but hopefully you only have your Xbox360 and your computer)
and now save your setting and restart your Xbox360 and there you go NAT open. This also help if you get any kind of  LAG while someone is on the computer using the internet, your Xbox360 will be high priorty to the router.
HOPE THAT HELP
