NAT Type moderate

So you have two solutioins xSimpleDRIFTERx:

1) Upgrade your linksys WRT54G to one that has software on it that supports multiple xboxes.

1a) Dlink DIR-655 works very well and can vary in price between $50-$100 or

1b) Netgear WNR2000, around $50-$60, (either v2 or v3 plus log into it and set the NAT filter to OPEN when your configuring it for the 1st time)

1c) Another router on the page Shad0wManUK linked.

2) Open ports to a single xbox so it has Open NAT and let the other one have strict or Moderate.

P.S. NAT does affect connections to dedicated servers like Xbox LIVE itself, Netflix, Youtube or other Apps or games

with dedicated servers, most notably games from EA. It only affects the other PEOPLE on live that you can connect to.

P.P.S. If your you have a DSL connection your modem is likely a router also and regardless of either situation, you'll need to forward ports from your modem to your router.

WRT54G

^ That will only give an Open NAT to that Xbox though, it will just shift the problem to his brothers setup

To awnser your question: 'No it wil not fix your NAT problem'...

Can anyone verifie that! ;-D

But your next question would be how to open your NAT settings.

The awnser is not that difficult. But your have to know how to navigate your router.

Go to your Xbox --> Settings --> System --> Network Settings --> Configure Network

Now you see the IP adres of your Xbox 360 and you see Gateway.

Write down there 2 numbers.

The Gateway is your router's IP, the IP adres of your XBox 360 you need to open the ports.

Open a browser on a PC that's also on your home network, now just enter the Gateway adres, like:

http://192.168.168.0

Press 'enter', now log in to your router, go to Port Foward.

Open the following ports:

TCP 3074

UDP 3074

UDP 53

UDP 88

To the IP adres of your Xbox 360 you wrote down.

Save these settings, and you're ready to game with an open NAT!

When ever you have problems with this again, make sure you check if your IP adres of your Xbox console didn't change.

Good luck!

Unlikely to get an Open NAT on multiple Xboxes or Games for Windows (same thing) you need the right type of router, which is why I was asking what router you are using:-
