Is there a fool proof way to tell if a port is closed? The Azureus test says it 'may be'!Are there ports that are better than others for PFing? TKS Tom

Use Shields Up! at grc.com to test for open or closed ports. Since it's at a remote site on the Internet it "sees" your system as a peer would.

There are no better or worse ports for forwarding. Just avoid any that are reserved. This site has good info on forwarding for many applications and routers:

@ScottW,

That last site you referenced (portforward) is a good one.
Hadn't seen that site before.
GREAT Bookmark !!!!

Thanks.

Kindest Regards,

ScottW-Thanks.Shields Up only checks the first 1056 ports (as far as I can tell).I did find out that my system is abnormally secure,so that was great news!How do I tell if the port I'm using is reserved?TKS again Tom

"netstat -a" at the command prompt will give you a list of open ports

Rick-forgot the space before the (-).The port isn't listed.I'm assuming port forwarding isn't working.TKS

Tom, you can specify a port or range of ports to check with Shields Up! Type the port number(s) into the text box in the center, then click on the "User-Specified Custom Port Probe" button.

ScottW-Test came back 'stealth' and unknown protocol - unknown application.Am I back to square one?I was downloading at 40 KB/S on Verizon (tested at 1425Kbps down - 208 up).Does this mean anything or too many variables? Tom

Were you running Azureus when you tested the custom port number? If your setup is like mine, then you won't see that port open until the application that needs it has asked for the connection. Run Shields Up! while Azureus is working in the background and you should see the open port.

There are too many variables to know if 40 KB/s is a good download speed for you. It depends on the torrent, how many seeds, how many peers, the bandwidth available from all of those seeds and peers, and so on. Some ISPs throttle P2P service when or if they can detect it.

If it says stealth then that means you have a firewall that is hiding the ports being open or closed. Which is a good thing security wise. Unfortunitly it means you can't use that test to see if the port is open or not.

Tom, the post from jd2066 reminded me of something. If you have a software firewall that could block the port, then you would need to tell it to let Auzureus through. The router in your Westell 6100 acts like a firewall and requires port forwarding. A software firewall on your system, even the built-in Windows Firewall, will block traffic as well unless you tell it to allow a program or port to open.

ScottW and jd-The port failed the ping test making it visible on the net but still says 'stealth' (shields up detected a ping).Only one firewall ( Windows) and it's allowing Azureus.Does this mean I'm set to go?TKS Tom

Well, I suppose it's possible that the open port is stealthed to ICMP (ping) packets but is open to P2P packets. I have never seen such a thing. Even if that were the case, the port test in Azureus should check for P2P packets not pings. If the Azureus port test is failing, I don't think that you have accessibility and you won't get the best performance.

Does the Azureus port test display any status?

ScottW-0 ports open
0 ports closed
1 port stealth
'Port tested was found to be in stealth'.

I think this can be mark "solved' as I'm getting up to 166KBs when downloading direct from Azureus and up to 60KBs from the feeder that I'm downloading a huge program from.I believe the feeder is a little slow.Thanks to all! Tom
