I have a Cisco ASA 5510 with three Ethernet interfaces. I am going to use the unit for ponit-to-point IPSEC VPNs between us and customers. I have one customer that wants to have an IPSEC VPN with a pre shared key of their choosing, and another that will want to do the same!!
I know (or think) that you can only have one crypto map per physical interface. If this is correct then can I have more than one preshared key per physical interface, so I can cater for both customers on the same interface with the same crypto map but different pre shared key? Or do I have to have a different physical interface and public IP per client that needs to do this?
Is there a concept of sub interfaces or not?
I have no clue!! Any help would be much appreciated.
