Titolo: Sempre su 2 Schede di rete per un Linux Firewall

Allora... finalmente sono riuscito a reinstallare Linux con le due schede di
rete... aggiornando pure il driver fornito da 3com...
Niente di particolare insomma... Ho ricollegato il PC Firewall al router...
entra in Internet che è una meraviglia ma.. la mia rete interna non ne vuole
sapere quindi vi descrivo il risultato dei comandi:

Allora, per intenderci, 151.83.31.5 è il server NT... 151.83.31.2 è
l'indirizzo IP del Firewall all'interno della LAN, 10.0.0.2 è l'indirizzo IP
del Firewall con il Router, 10.0.0.1 è l'indirizzo IP del router
Se qualcuno mi sa dare una mano a far si che Linux riesca a vedere pure la
mia LAN...
Grazie a tutti
Alberto
P.S. Dopodichè il passo sucessivo è far si che tutta la mia LAN riesca ad
uscire in Internet passando tramite Firewall e, sempre tramite quest'ultimo,
vorrei limitare l'utilizzo di Internet ai vari utenti... tipo proibire
l'accesso ai siti di Trading On Line...
Pensavo d'usare IPCHAIN... cosa ne pensate? C'è uno strumento visuale che
può essermi utile? Anche perchè tra qualche mese abbandono qui il posto e
gli altri, non essendo esperti Unix (come per altro non lo sono nemmeno io,
ma cmq qualcosina in + rispetto a loro ne so...!!!!), dovranno malgrado loro
prenderci familiarità.
Ringrazio tutti anticipatamente
Alberto

The answer is: "NO!"
