Ciao,
Ho messo in piedi una VPN IPSec standard con isakmp sul mio pix 501.
Tutto funziona a dovere a patto di far puntare i client VPN sulla wan del pix.
Dato che il mio provider mi gira anche un ulteriore ip pubblico mi servirebbe poter far connettere tutti i clienti su quest'ultimo ip pubblico invece che sulla wan del pix.
La mia attuale configurazione è la seguente:
PIX Version 6.3(5)
interface ethernet0 100full
interface ethernet1 100full
nameif ethernet0 outside security0
nameif ethernet1 inside security100
enable password XXXXXXXX encrypted
passwd XXXXXXXX
hostname Pix
domain-name XXXXXXXX

Ciò che sto cercando di fare è far instaurare la VPN facendo puntare i client esterni sull'ip che mi ruota il provider (che è ho messo per il nat global).
La cosa è possibile ? Io stavo cercando in giro se esiste un comando per indicare l'ip di ascolto per la VPN...ma non ho trovato nulla.
Grazie in anticipo per i consigli...
ciao.
Phelton
