It won't make your computer invisible (as your open ports will still respond to a port scan), makes extra work for you, and breaks the rules of RFC 791 (TCP).

It is most definitely NOT a foregone conclusion!Lets say a company has a /24 but they only currently have, say, 143 computers active (workstations+servers). Since 'Stealthing' is non-standard behavior for Internet systems, it is behavior which must be created and enforced by means of a firewall security system of some sort. I knew this site would come under significant attack by Internet "baddies" who would want to bring it down.

What if I want to access other files but not share any of my own? Where do you get NAT routing? But your ports are still closed so see (1.) 3) Your ports are all closed or all stealthed except for one. Connecting to my iMac internally on my network works perfectly.
However, the "All Service Ports" @ GRC.com shows stealth for all except for two ports showing as closed. I'm just curious why these two ports report as being closed. Does your modem have a firewall.

My friend has all ports as stealth - I have almost all of them as closed. tests and adding a firewall I went to www.anonymizer.com and it saw all sorts of stuff! Once you set up logging you can run the test or just test those ports and see which packets the router receives from grc.

Just to annoy/confuse an attacker 7) Respond inconsistently and randomly. When someone attempts to connect to a TCP port (sends a SYN packet) that you do not wish to allow a connection to, you have a few choices for your response:
Completely stealthed on both platforms.Tryed to emulate original conditions by turning off the Win7 rig, and ran scan on XP but no change - still all stealthed. That's the consequence of using any of the Windows NetBIOS resource sharing clients without a firewall. I don't like this solution, though, because it requires that the ICS machine always be running to provide NAT services for the rest of the network. The machines on this private network (behind the NAT router) use IP addresses that have been set aside for just this purpose.
When I run the Shields Up test, it shows three stealthed ports, 0, 80, & 135.
