A question comes to me and I don't have the answer but I know that you
guys will. If I have a router in front of my ISA/SBS server that only
allows 4 ports through, how is it that all port scans are reported from
IP addresses at Microsoft and the ISP on my ISA server? Is it a false
positive? If so, what in the world causes it when there are only 4
accessible ports?
