I am still new to pen-testing, and would like if someone can explain to me why 2 OPEN ports (ftp and dns) get listed as closed when I run a port scan using nmap (linux version) on a host sitting behind our firewall.
Two other ports which are open (ie http and https) returned as open, quite correctly. Why is nmap getting confused with ftp and dns ports which remain open ?
