Avrei però la necessità di inoltrare alcune porte sulle macchine interna alla lan ( porte diverse per macchine diverse).
Prima utilizzavo questi comandi
Codice: Seleziona tutto
ip nat inside source list 1 interface Dialer0 overload
ip nat inside source static tcp 192.168.1.2 46661 interface Dialer0 46661
posto anche la configurazione che sto utilizzando sperando che qualcuno mi possa aiutare..
