Passiamo al problema di configurazione che ormai da diversi giorni mi ha portato via il sonno
Sono collegato a internet con Router Atlantis WebShare 440 , dietro poi c'è un Cisco ASA 5505 .
Naturalmente dietro questo Firewall c'è tutta la mia rete domestica.
Ho nattato con successo tutte le porte che mi servono dal Router al Firewall. Praticamente riesco ad utilizzare tutto quello che mi serve, tranne un server FTP installato su un computer della mia rete domestica.
Escludendo l'asa (lasciando il pc collegato direttamente al router) e provando a raggiungendolo da remoto non ho problemi funziona tutto, mentre con il firewall di mezzo non c'è soluzione.
Naturalmente ho nattato tutto con successo infatti mi funziona alla grande TFTP server, RDP, Vpn, e tutto il resto... solo questo dannato
server FTP mi da problemi.Codice: Seleziona tutto
Breve configurazione della Rete:
Router ip 192.168.1.254
Firewall outside ip 192.168.1.253
Firewall inside ip 10.0.0.254
Pc con server FTP ip 10.0.0.2 Provo a postarvi la configurazione del mio ASA:
Codice: Seleziona tutto
ASA Version 8.0(4)
