Isp Is Spying On Me ?

They( the ISP) are not scanning you. This is a bug and a vulnerability that exists in early builds of sygate and windows XP/NT . Upgrade to 5.1 and you shouldn't have a problem any more.
The specific bug in the NT kernal of your system allows another computer on your own gateway to access some kernel components. In some cases it could be an attack being "proxied" at you.

You're all getting a bit too paranoid for your own good.

Then the vulnerability/ bug must lie in sysgate itself.
Block it and if it kills your internet connectivity, unblock it, check all updates are installed in windows and your firewall. It's as simple as that.

Or do what the article suggests with the advanced ruleset. Change it to meet your system requirements if neccesary.
