ASM not working when Implementation Load Balancer (Barracuda) under ASM

Actually now we use ASM without LTM and its working well. But we have a problem when we put Barracuda Load Balancer between ASM and Origin Server (2 Origin server), the problem is request never display on browser. Any body have experience with implementating ASM and Load Balancer? is there any extra configuration in ASM?

This is our scheme:

Users from outside(internet) -> ASM (10.0.32.200) -> Load Balancer (10.0.32.30)-> Origin Server (10.0.32.10 or 10.0.32.20)

This is the detail:

ASM Self-Ip : 10.0.32.50

Virtual Server(Inside ASM) Ipaddress : 10.0.32.200 pool/node : 10.0.32.30 (load balancer ip)

Load Balancer Ipaddress : 10.0.32.30 *10.0.32.10 service all (origin server 1) *10.0.32.20 service all (origin server 2)

Origin Server1 Ipaddress : 10.0.32.10 subnetmask: 255.255.255.0 gateway : 10.0.32.50 (ASM ip) Origin Server2 Ipaddress : 10.0.32.20 subnetmask: 255.255.255.0 gateway : 10.0.32.50 (ASM ip)

So when user access/request page to the Virtual server ASM (10.0.32.200) directly going to Load Balancer (10.0.32.30) and in Load Balancer will directed to origin server 1(10.0.32.10) or origin server 2(10.0.32.20) and Gateway from my origin server is direct to ASM self-ip (10.0.32.50). but the problem is that request never display on browser.
