Re: Westell port question
That's how they should behave.
Without forwarding, they would probably show as stealth (no response).
With forwarding, if the program is not running your operating system refuses connections (port is seen as closed).
With forwarding, and the program is running, your operating system accepts connections for the program (port is seen as open). |

| With some routers, an unforwarded port simply shows as a closed port. With others it shows as stealth.
Once a port is forwarded to a computer internal to your LAN, that computer is now in charge. If that computer happens to be running a firewall that drops all packets for that port, it will show as stealth. Otherwise it will show as closed unless there is a program listening on that port (when it shows as open).
If the port is forwarded to a non-existent computer on your LAN, it will show as stealth.
That's just the way TCP works.
I'm not sure what you are looking for. A port cannot show as open, unless there is software listening on that port and accepting connections on that port. That's pretty much the definition of "open".
