If SU can tell that the port is closed, then it's being forwarded |
| 15 |
correctly. Otherwise, SU would show "Stealth" for the port status |

(meaning it cannot tell if it's closed or open.) |

"Closed" means the application that listens on that port is not running, |
| 19 |
or is not answering. But the port has been forwarded. |
