I have some servers working on my system such as web, ftp, pop, smtp. When an intruder scans my IP adress, I want those servers to be safe and do not appear at the scanner program. For this reason I have installed ISA Server, configured a Protocol Rule that allows only http, and at the Publishing section I've defined a rule for each of my servers. But when I scan my IP adress, those servers' ports appear clearly, they are not hided. As I said when scanned I don't want those ports to appear at the scanner software. So which configurations do I have to do at ISA server?
