Salve a tutti
ma l'apparato in oggetto, permette di far accedere un client remoto collegato in VPN alla rete del pix dove è configurato, in modo da far navigare il client oltre che nella rete inside del pix, anche nella outside e principalmente in internet con l'ip pubblico della rete del pix e non con l'ip pubblico del client?

Ringrazio per l'info

si.

Grazie mille per l'info
Se posto la mia configurazione, riesci a dirmi perché dal client mi collego alla VPN, accedo solo agli host dell'inside, ma non quelle dell'outside, e cosa principale non navigo su internet con l'ip pubblico della VPN, ma con quello del client.

Grazie mille in anticipo

Di seguito la conf

Grazie ancora in anticipo

Nessun altro riesce a dirmi come risolvere il problema sopra descritto modificando la mia attuale configurazione?

Forse in relazione a quel che mi serve, e a quanto mi ha confermato ZOT, la soluzione è nella risposta di questa persona:

VPN users cannot browse the Internet through the VPN. Traffic that enters the PIX on an interface cannot exit on the same interface.
Workaround:setup split-tunneling, so that the VPN user uses their own Internet connection, and only routes traffic destined for the corporate LAN over the VPN.
vpngroup GROUPNAME split-tunnel accesslistname
Where accesslistname is an access-list that defines traffic going from your corporate LAN to the ip pool you have setup for the VPN users.

Keep in mind, this is a security risk, because anything that can touch the VPN users' computer over their Internet connection, now has a link to your corporate network.

HTH.
