Moving ASM to Standalone Configuration

I can tell you that we have something similar currently deployed. Our LTMs and ASMs are on seperate hardware. Basically we run LTMs and ASMs in our DMZ and then LTMs on the internal network in front of the servers. So the traffic for an external facing web application hit the LTM gets load balanced to an ASM and the ASM runs the traffic through policy, then sends the traffic to an internal LTM pool which load balances it to a server. This design has worked pretty well for us. Let me know if you have any specific questions
