Hi there, I have recently moved to a new apartment, and after connecting my computer to the Internet I tested Look'n'Stop at the GRC website (ShiedsUp! test). Almost all of the first 1056 ports failed the stealth status (all ports but 4 are blue, which means they are closed but not invisible). It has never happened in 5 years, and I wonder what could be the cause. As far as I know my connection is behind a router which is pre installed by the condominium and had been checked by a technician when I moved in. Any ideas as to what might be the cause for not achieving a stealth status? L'n'S is configured with "EnhancedRules Set", all "advanced options" are checked, my system is Vista Ultimate 64 bit. I even tried Windows Vista own firewall with the same results. Thanks in advance for any suggestions.
