Titolo: Configurare Pool di IP pubblici su ASA

Ciao a tutti,
ho configurato ultimamente un ASA 5505, l'unico problema ï¿œ 
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 perï¿œ 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'ï¿œ qualcosa d'altro che va configurato per utilizzare 
gli IP pubblici a disposizione?
grazie
ciao
Andrew

 tranne l'interfaccia stessa dell'ASA il resto degli IP non fa le NAT.
Che vuol dire?
Prova a postare la configurazione

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
