Hi all, i have a question, i make a firewall but when i make a scan using nmap it returns to me that the ports are in state filtered no close (The 1673 ports scanned but not shown below are in state: filtered) Anybody know why it returns to me it? is my rules wrong? or is a type of rule that i created that make it in state filtered? Just the ssh/22 port is open, and if i make a internal test in the firewall i can see another ports opened, its good because i just can see my ssh port opened from the internet, but i dont understand why the state show me filtered. thanks
