Imas sve lepo objasnjeno na tom sajtu, sta znaci open, sta close a sta stealth. Cim si proverio odredjeni port dobio si rezultat, a za skrivene(stealth) portove izlazi, citiram:
Your system has achieved a perfect "TruStealth" rating. Not a single packet — solicited or otherwise — was received from your system as a result of our security probing tests. Your system ignored and refused to reply to repeated Pings (ICMP Echo Requests). From the standpoint of the passing probes of any hacker, this machine does not exist on the Internet. Some questionable personal security systems expose their users by attempting to "counter-probe the prober", thus revealing themselves. But your system wisely remained silent in every way. Very nice.
To sto je port sa stealth statusom znaci da firewall dobro obavlja svoj posao jer takav skriveni port, moze biti otvoren ili zatvoren, zavisi kako je podeseno ali ne odgovara na spoljne upite (ICMP Echo Requests)
Npr. ja sam na ruteru forward-ovao neke potove za dc++, torrente i sl. i za sve njih dobijam rezultat da su stealth, pritom kada pokrenem te programe konekcija je ok.
ovo sam dobio od uTORRENT
