Ciao a tutti,
visto che mi avanza un 2651XM volevo sapere se lo potevo configurare come firewall in modo tale da poter sostituire il pc (sempre acceso) sul quale ho configurato il mitico IPCop.
Secondo voi può funzionare ?
Grazie e a presto !!!
IK
2651XM come firewall.

Dipende dal IOS che monta. Riguardo le prestazioni una bestiolina in quel modo non dovrebbe avere dei problemi particolari. Cmq aggiorna l'ios all'utima versione con le features ADV. SEC. e vai tranquillo!

Allora ho verificato la versione di IOS presente. E' la c2600-ik8o3s-mz.122-11.T.bin ovvero, secondo il sito Cisco, adatta più o meno alle mie esigenze.
la conf attuale è:

Mentre per bloccare intrusioni ed accesso vpn ho qualche dubbio.

Beh, la ios è un po' vecchiotta...dato che deve fare da firewall io la aggiornerei!

E' questo cosa significa?Procedendo con ordine dovrei attivare i vari forwading.
Mentre per bloccare intrusioni ed accesso vpn ho qualche dubbio.
Devi effettuare del NAT statico in ingresso?
Accesso alla VPN non è configurato di default e pertanto non c'è niente da disabilitare!!!
Ti consiglerei di configurare il CBAC o "archebugi" simili e i "vari inspect" (IDS per intenderci) nonche il logging.
Nella parte della Documentazione del forum esiste un documento carino fatto dalla NSA che potrebbe essere un ottimo punto per iniziare!

Rieccomi, nel magazzino della ditta dove lavoro ho trovato un altro 2651Xm (forse migliore perchè ha 128Mb di RAM e soltanto 16 di Flash), in compenso ha una versione di IOS più aggiornata ovvero c2600-ik9o3s3-mz.123-18 .
Purtroppo, nonostante la configurazione guidata di SDM e qualche mia scarsa conoscenza dei comandi, il router non ne vuol sapere di funzionare. Non mi permette di navigare su nessun sito, ricevere posta, ecc. Proprio non và !
Questa è la conf attuale e spero tanto in un vostro aiuto.
