Can't get into a game

i can never find any players to get into a game. Someone help please!
i heard it is because of bad ping or something like that but i dont have bad connection. im in southeast asia btw.

Is your NAT type set to open? If it is Strict then you will experience difficulty in finding games with any multiplayer game. Contact XBox and your router manufacturer(In this order) so you can open up the required ports so it will be set to Open.

By the way: Your NAT type is shown when you hit Crossfire off the main menu towards the SE part of your screen.

Hope this helps
