If you can't understand that..
Name: XBox 360. (technically, you could reserve all of your consoles, and just have a whole range, and have it all set for the same priority.)
Priority: 64 (I wouldn't set it to 1)
Local IP Range: 192.168.0.x - 192.168.0.x (if you reserve your XBox 360's, you can set a whole range)
Local Port Range: (this should be greyed out, if you chose ANY)
Remote IP Range: 0.0.0.0 - 255.255.255.255
Remote Port Range: (this should be greyed out also)
