mi è stato chiesto di fare una particolare configurazione su un pix per far accedere ad una serie di servizi il mio cliente. In sostanza si tratta di accedere ad un vpn concentrator il mio pix 515e, ma per poterlo fare devo accedere con un indirizzo pubblico che non è i lmio (mi è stato asseganto dal gestore dei servizi), ovvero devo 'far finta' di avere un indirizzo diverso da quello con cui esco per collegarmi al peer. Mi hanno comunicato:
1) Indirizzo remoto con cui il loro concentrator crea la vpn.
2) Indirizzo con cui fare nat assegnato a me.
3) Indirizzo loro con cui fare la vpn.
4) PSK
5) Tipo di crittografia.
6) Subnet ruotate.
Il collegamento verrà effettuato con VPN IPSEC con PSK in 3des esp/sha/hmac-160. Inoltre devo 'routare' 7 subnet (che vorrebbe dire
). La mia conf attuale è questa:
