I have request for an unusual design, and I do not know if there is a solution.
I need to tunnel several applications between 2 ASAs, each application corresponding to a dedicated vlan behind my first ASA. The customer explicitly requires dedicated VPNs for legal and liability reasons, hence in theory I would need 3 tunnels between the same ASA peers.
I have searched in the literature but it seems that ASAs won’t allow for multiple VPNs between the same peers.
Would you have an idea on a possible design? Can I put 3 interfaces of my second ASA on the same network and pretend these are distinct hosts?
