I'm demoing different software firewall applications and decided to run some of the different online tests for comparative purposes. So first, I decided I needed a baseline as to what I look like unprotected. Normally I run behind a linksys router, so I unplugged from that, disconnected the router from the dslmodem, and plugged directly into the dslmodem (of course reconfiguring all my ip info). I turned off any firewalls, and the only security related app I had going was NAV2002. I ran tests at GRC, Security Space, PC Flank and DSLReports, and every single test came back with a perfect score of either "0" or "all stealthed". I run XP Home and have the XP Firewall disabled. How can this be? I really don't understand these results. I was expecting to see a bunch of open and closed ports, but not stealthed. I'm really at a loss as to how to proceed, as I now have no basis upon which to differentiate the effectiveness of different firewall applications. How can I get "unstealthed"?
