HELP Cisco 2811 + WIC ADSL +16 IP Pubblici
Inviato: mer 02 gen , 2008 11:51 pm
Ciao a tutti ,mi trovo nella spiacevole situazione di chiedervi aiuto per la configurazione di un router Cisco 2811 per la connessione ad una adsl telecom con 16 ip fissi.
Ho provato anche con il cerca del forum , ma provando varie configurazioni non credo che sia riuscito a configurare a dovere il tutto.
Le mie domande sono queste:
E' giusta questa configurazione?
Come faccio a vedere se e' ok ,ho provato a fare un ping 4.2.2.2 dal router ma senza successo.
Se devo assegnare degli indirizzi pubblici alle macchine collegate la configurazione e' giusta?
Vi ringrazio dell'aiuto che mi date.Anche perche sono nel panico piu' completo e non so' dove mettere le mani.
Non vi nego che sono anche un CCNA ma non lavorando da molto tempo con Cisco e la comandistica ho totalmente perso la dimestichezza con questi apparati.
Veniamo a un po' di dettagli.
Connessione:
Tipo di contratto: Alice Business (lo so' non e' il top ma l'azienda per cui lavoro mi passa questo
)
Indirizzi Ip assegnati: 88.54.182.80 Network Mask: 255.255.255.240
Default GW: 88.54.182.81
Punto Punto: 88.54.83.42 Network Mask: 255.255.255.252
