I am interested in having all ports stealth, to avoid malicious attacks on the old Windows PC I have brought back out of storage and updated.
In the "Stealth Ports Wizard" I selected "Block all incoming connections and make my ports stealth for everyone".
GRC Shields Up! reports port 0 and port 1 are "closed" not "stealth". They are only "closed".
All other ports are "stealth"...
Here's my recent experience with this issue that may lead somewhere.
I run 2 rigs XPsp3 & Win7sp1 through Internet Connection Sharing(ICS) on the XP rig that is running CIS 5.3.181415.1237. Internet via Cable modem.
I'm used to seeing a clean report from GRC Shields Up!, but noticed that since I connected my second rig through ICS I get back a 'Fail' from Sheilds Up! because port 0 & port 1 status is 'closed', but not 'stealthed'.
When I first ran the Shields Up! scan from XP, my Win7 rig was powered off. When I turned the Win7 rig on and ran Sheilds Up! from it - I got a clean scan, all passed inc. ports 0 & 1. Meanwhile... back to the XP rig and I got a clean scan there too! 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. Then I switched OFF ICS in 'Local Area Connection Properties' (see attached pic) and bingo. Sheilds Up! reports ports 0 & 1 as closed, but not stealthed.
I'll come back if I can get a better handle on what's going on. Ideas from all very welcome.
