You have to use a VPN technology that supports netflow on the router. Virtual Tunnel Interfaces is the one we use on CISCO 2900/1900 running v15 whatever IOS. We use routers at both ends, no ASA for these. You'll have to verify if the IOS you run supports VTI and if the ASA can also use VTI. Same for any other methods that support netflow. You also have to buy the correct version of IOS if you want tunnels that can go above 8Mbps
