Xbox 360 moderate nat?

well i enjoy playing halo 3 and very often it says my nat is moderate but when i first got my xbox and router it was great





i have a linksys router and it says its model is wrt54g and my computer has windows xp on it





when i play on matchmaking it says something about nat not being open and it can effect the game and alot it just lags so bad like it says spawning in 5 seconds for a long time or my enemies just walk in a strait line doing nothing, and in gears of war its just awful trying to play if im not the host





so if anyone can help me with simple terms on how to fix this i would really appreciate it

Check your router settings..





On the Administration %26gt; Management screen at the bottom is UPnP.. Set that to Enabled.. click Save Settings.. and you should be good to go..





UPnP (Universal Plug and Play) lets your Xbox 360 open the ports it needs through your firewall.. it will bump you to Open NAT..





The Administration %26gt; Management screen is described on pages 17 %26amp; 18 of the manual.. (link below for the WRT54G manual.. it takes a long time to load..)





Good luck..
