I have a client who recently purchased an SA 540 to replace an old Sonicwall, they had a vpn connection with a medical software company on the old device. The software company says the inside interface of the vpn needs to be a routable (outside ip) as opposed to the usual inside being a private address. My understanding is that the inside address of my side of vpn would be an outside address that would then be natted to the server. A friend of mine who is vey experienced with Cisco says this can be done on the ASA devices as he has had to do it with several financial companies vpns to his company but not sure about SA 540 as he has never seen one. Does anyone know if this can be done on SA boxes and if so how to configure it.
