Hi everybody. I'd like to be able to understand this. I use XP Pro w/SP2. D-Link router hooked to cable broadband. I know when I test for leaks and stealthed ports I'm really testing either the cable company or the router. So I go to PC Flank and pass all of their tests. I'm locked down tight. Except that when I use their Quick Test it finds four ports open. Why do I pass all the other test at PC Flank and fail their Quick Test and how do I fix this? I have tried this with a bunch of software firewall including Comodo. Thanks for my continuing education.
