Sheilds Up...?

My PC failed because of Port 0... How is that blocked or stealthed?

What firewall are you running?

Windows

Here is a reference from the GRC site: https://www.grc.com/port_0.htm

Windows firewall is know to leak in some cases.

Thanks, I read up on it after the test.

I disabled the router firewall and ran the tests using Comodo. I still passed 100%

Each router brand has its own firewall set up here is mine. Note that I have unchecked netbios both outbound and inbound and I have checked stealth mode.

I can't get this screen

Each router brand has its own screen setup. Assuming you are behind a router, it appears from your screen shot that your ISP, Verizon, has that particular setup for the router they are supplying.

I notice your screen shot is of the general page and low security is selected. Have you explored each of the tabs below General, particularly Access Control, Remote Administration, and Advanced filtering, see what these tabs offer?

If Verizon has a help line, you might consider calling them and letting them talk you through securing your router. Since all I have to go on is the screen shot of your general page, it is difficult to make a recommendation.

It appears to me that the router security setting is weak. I think you need at least the medium setting and possibly the high setting is equivalent to the security I have set up on my router. Unless you have a specific need for remote administration, you want that blocked. Perhaps the Access Control page will allow you to block netbios?

I suggest you go to GRC's Shields Up and test your current low setting. The test will show you if your computer can be seen from the internet. It will also tell you which ports, if any, are open to the internet and thus vulnerable. Go to GRC|Gibson Research Corporation Home Page, scroll down, and click on ShieldsUP. Run each of the first three tests. These will tell you how secure you are. What you want is for your computer to be invisible from the internet and have no open ports.

You might also set the security level to Maximum and run the tests a second time. If setting the security level to Maximum does not adversely affect the way your normally operate your computer, I would leave it set to Maximum. The Maximum setting allows you to use email, your web browser, and file transfer.

Let me know how your tests come out.

Very good. I am waiting to see your results.
