My Cisco ASA terminates at the gateway of my network. Behind the Cisco ASA I have a Cisco Router. I am trying to configure virtual interfaces on the router to my ASA with multiple VLANs. I imagine that I will need to have some sort of trunking involved. Can you advise that If i would need to issue an encapsulation dot 1Q command from the routers interface to the firewall? I tried it, but I feel like there needs to be some trunking involved for this to work.
