Pentest-tools ti fornisce tutta una serie di tools per verificare la sicurezza della tua rete, tra cui portscan dalla 1 alla 65535...nel mio caso si blocca quasi subito (probabilmente perché sul mio firewall hardware sono impostati i parametri anti-flood & anti-ping TCP/UDP

Primo test TCP:

Starting Nmap ( http://nmap.org ) at 2017-05-17 14:27 EEST
Initiating Ping Scan at 14:27
Scanning [...] [4 ports]
Completed Ping Scan at 14:27, 1.34s elapsed (1 total hosts)

[+] Nmap scan report for [...] [host down]
Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn

Nmap done: 1 IP address (0 hosts up) scanned in 1.41 seconds
           Raw packets sent: 8 (304B) | Rcvd: 76 (4.969KB)

Test rifatto con il parametro -Pn:

Test UDP (sempre con il parametro -Pn):

Da quello che leggo la porta 30005 è aperta, non so il perché.
Come dovrei interpretare le altre righe che ho evidenziato in viola?
