Hi Does anybody know a port scanner that could distinguish a "deny" filtered tcp port (firewall drops packets for the port) from a "reject" filtered tcp port (firewall returns an ICMP - port unreachable)?. Nmap seems to report boths cases simply as "filtered". Actually, both cases are filtered, but when you receive a ICMP, you can be sure that the port is really filtered. If you do not receive nothing, the port could be filtered, or packets could have been lost...
