I use a Belkin wireless router at home, and no matter what I do, I can't seem to achieve the so called "stealth" status. There are 4 client computers connected to the router via ethernet or wireless adapters, and DHCP is enabled. I set the firewall on the router, and also have it block ping requests.

I have a software firewall installed (zone-alarm) and it's set at "High" for the internet which reads as "stealth" status.

Still, when I test the settings through Shields Up!, my ports are just "closed", not "stealth-ed"

It may not be a big deal and I don't think any hacker would try to break in my home network for my "precious" data, but from a geek's point of view, it's sort of annoying that I can't achieve the stealth mode!

Funny thing is when I had a Linksys router, all of my settings were stealth even without software firewalls. But I had alot more troubleshooting nightmare with that.

So my question is, what should I do to achieve the stealth mode? I have a Belkin router. Is it a limit on the router's part or do I need to do something? What would be the difference between the Linksys router and the Belkin router?

I'd appreciate any input. This thing's been quite puzzling for me.

Stealth means nothing. Don't worry about it. Geeks don't care, they know the truth.

Agreed. Steve Gibson has a habit of talking out of his ass on many subjects.

I sort of figured that.. However, the question still remains. What in the hell makes the difference? What becomes "Stealth" and what becomes "Closed"?

If the destination drops the packet instead of responding by letting the source know that nothing's going to happen, it's considered "stealthed."

What stealth tells people is: There's something here, but it isn't responding to your probes.
What responding correctly tells people: There's something here, but it isn't listening. Thanks for stopping by!

strange, i'm only running a single hardware D-link 704P and i have stealthed every single port EXCEPT the 113. But the 113 is stealthed when i enable a software firewall

Edit: did you try the file sharing service for shields up, what did you get?

I got :

Your Internet port 139 does not appear to exist!
One or more ports on this system are operating in FULL STEALTH MODE! Standard Internet behavior requires port connection attempts to be answered with a success or refusal response. Therefore, only an attempt to connect to a nonexistent computer results in no response of either kind. But YOUR computer has DELIBERATELY CHOSEN NOT TO RESPOND (that's very cool!) which represents advanced computer and port stealthing capabilities. A machine configured in this fashion is well hardened to Internet NetBIOS attack and intrusion.

Unable to connect with NetBIOS to your computer.
All attempts to get any information from your computer have FAILED. (This is very uncommon for a Windows networking-based PC.) Relative to vulnerabilities from Windows networking, this computer appears to be VERY SECURE since it is NOT exposing ANY of its internal NetBIOS networking protocol over the Internet.

Find the ports that aren't stealthed and forward them to a non existant computer.

It doesn't do anything. If your system is stealthed, it screams, "I'M HERE!" If your firewall responds properly it does about the same damned thing. So what benefit to stealth is there? It doesn't hide you, it MAKES SURE PEOPLE KNOW YOU'RE THERE. Oops.
