An open port is when something can create a TCP connection (UDP is there, too, but for simplicity sake keep it TCP). If you have a public 1.1.1.1 on an Airrouter and the customer is NATed at 192.168.1.100 by default the only open ports would be to the router - 80 and 22. Now if you dstnat 3209 to the Xbox and the Xbox is listening, you then have an open port. If the Xbox is off, the outside will see it as a closed port.
