NAT e iMac

Inviato: ven 09 nov , 2007 4:25 pm

Salve, un consiglio per favore ... ;)

In LAN ho un iMac con IP 192.168.1.244
che ha funzioni sia di web server che ftp.
Tutto funziona bene.

Nella stessa LAN ho anche un PC con Linux e
IP 192.168.1.3 che ha funzioni sia di web server che ftp.
Tutto funziona bene.

Sul router Cisco 857 ho configurato la NAT con
due IP pubblici a puntare le due macchine singolarmente.
Le impostazioni sul router sono identiche.
Succede pero' che dall'esterno della LAN,
ovvero da internet, il PC con l'IP pubblico viene visto
e funziona regolarmente mentre l'iMAC non risponde,
ne' al web, ne' all'ftp e neanche ad un semplice ping.

Sul router il firewall e' configurato allo stesso modo
e sull'iMac e' tutto aperto e condiviso.

Non so piu' cosa provare per far vedere l'iMac,
qualche consiglio?


Grazie.



saluti

Come al solito dobbiamo vedere la configurazione del router in questione...
