Purtroppo non ho mai avuto a che fare con i prodotti Cisco prima d'ora e sono in difficolta' nel capire la configurazione.
La posto a seguito (omettendo alcune informazioni per la privacy):

Avrei bisogno di un benefattore dell'umanita' che mi spiegasse riga per riga (o blocco per blocco) il significato del codice nella configurazione.
Inoltre vorrei sapere cosa significa la riga evidenziata in rosso, come aprire le porte per utilizzare un client bittorrent (per il download delle ISO delle distro linux) e come abilitare un collegamento VPN tra il server in azienda e un palmare HP iPAQ hw6515 con installato Windows Mobile 2003.

Attendo speranzoso...

Ma un caffè no? Magari anche una pastina?!?!?

Anche una 4 stagioni se vuoi...
No dai, non so davvero dove sbattere la testa, sono noob completo sulle configurazioni dei firewall Cisco...
Forse mi sono espresso male, non pretendo che qualcuno si metta a spiegarmi in prima persona come fare, ma magari darmi qualche dritta o indicarmi tutorial o guide che lo spieghino bene...

Basta cercare nel forum (un pò di sforzo non guasta). Trovarai i link sulle ottime guide e la spiegazione a tutte le tue domande.

Ciao
