Still not stealth after using Stealth Port Wizard

I’ve used Stealth Port Wizard for Local Area Connection #10 which is my connection to my modem. After restarting I tested it on and it doesn’t seem to change anything because the results are the same as before I’ve used Stealth Port Wizard. Am I understanding its purpose wrong?

Here’re the results:

GRC Port Authority Report created on UTC: 2012-07-07 at 09:07:13

What is the make of your modem and the type of Internet connection you have?

I have a cable modem, no router.

Can you please post an image of both your Global Rules and Network Zones tabs. Please ensure that you make the Network Security Policy screen bigger in order to fit more information on the image, thanks.

Make and model, please? We need to make sure there isn’t a router inside your modem.

If your results aren’t changing when you use the stealth ports wizard, I suspect the test isn’t actually hitting the firewall.

You could do a really quick test by disabling the firewall and running ShieldsUp! again. If there is no change, it’s definitely not hitting your firewall.
