I am in need of some help. I currently need help setting up an ASA to terminate a site to site VPN using just one interface. I believe I can get this configured using hairpinning but wanted to see if anyone had experience configuring an ASA with VPN in this way.
I am currently running version 8.4.3 Here is a diagram of how I need the ASA to be configured.
You can use the subinterface and vlan concept to implement this
Instead of using physical interface for outside and inside, you can connect your physical interface to switch and configure that as a trunk to pass internet vlan and inside vlan, then configure interface vlan's on asa for outside and inside interface
