It appears that you have everything in the same network. I suspect asymmetric routing is causing your issue. Your ASM is routing the traffic through the load balancer to the origin servers, but your origin servers will respond directly back to ASM unless some source NAT is performed on the Barracuda load balancer. Your ASM will see responses from the origin servers when it expects to see them coming from the load balancer, so it drops the traffic.
I'd recommend checking the Barracuda configuration and configuring source NAT for these communications.
