Configurare Pool di IP pubblici su ASA

[Andrew]

Ciao a tutti,
ho configurato ultimamente un ASA 5505, l'unico problema ￜ
l'assegnazione del pool di IP pubblici. Avendo a disposizione 8 IP
pubblici ho configurato nella Global Pool dell'ASDM il range di IP a
disposizione. Peccato perￜ che non riesco ad utilizzarli per le NAT,
tranne l'interfaccia stessa dell'ASA il resto degli IP non fa le NAT.

Che voi sappiate c'ￜ qualcosa d'altro che va configurato per utilizzare
gli IP pubblici a disposizione?

grazie
ciao
Andrew

Che vuol dire?
Prova a postare la configurazione

255.255.255.255

ma se hai altri host interni puoi usare

static (inside,outside) ip_pubblico ip_privato netmask 255.255.255.255

ad esempio:

static (inside,outside) 64.61.216.20 192.168.22.251 netmask 255.255.255.255

e non dimenticare di aprire le regole in ingresso dall'esternbo per i
servizi che vuoi far vedere su 192.168.22.251
