Re: nmap status question

[Pete Hunt <lists () petehunt co uk>]

Filtered means that a firewall or similar is covering the port and stopping 
nmap from determining whether the port is open.

(Unfiltered means that nmap knows the port is closed and nothing is 
interfering with nmap's ability to detect it)
