Ciao a tutti

Ho configurato il firewall su una macchina debian linux via webmin come segue :

Accept If protocol is TCP and source is 10.10.10.2 and destination port is 3306 and state of connection is NEW
Accept If protocol is TCP and destination port is 10000 and state of connection is NEW
Accept If protocol is TCP and destination port is 80 and state of connection is NEW
Accept If protocol is TCP and destination port is 21 and state of connection is NEW
Accept If state of connection is ESTABLISHED,RELATED
Reject Always

Ma nmap mi dice che sono aperte molte porte

PORT STATE SERVICE
21/tcp open ftp
53/tcp open domain
80/tcp open http
110/tcp open pop3
111/tcp open rpcbind
113/tcp open auth
143/tcp open imap
548/tcp open afpovertcp
993/tcp open imaps
2049/tcp open nfs
3306/tcp open mysql
10000/tcp open snet-sensor-mgmt

Come mai? che cosa ho sbagliato o semplicemente non ho capito?

Grazie dell'aiuto
