Additional Info: Found out this is a Velocloud installation without the Premium License.
We need to establish a VPN connection to a customer who is using a VMWare SDWan solution. They do not have the license to specifically select the Cisco ASA as the VPN endpoint and are using the default "Non-SDWan Gateway" configuration on their side which uses a route-based VPN in transport mode with no VTI IP.
Is this type of connection supported from an ASA? I've done many route based VPNs, but we always have a /30 subnet on the VTI interfaces for routing. I've done extensive searching and can't find anything related to L2L IPSec VPN using Transport Mode on an ASA.
Any help is appreciated.
