Finally , I got it. RealServer talk to firewall with eth0, not VIP. Thank you.

Think about this: Client ----> FireWall(find MAC of LVS) ----> LVS(find MAC of RealServer) ----> RealServer(reponse with MAC of RealServer) ----> FireWall(What MAC of VIP in ARP table?) My question is , at last step: Will firewall check MAC of VIP? Or igore it? What MAC of VIP in firewall's ARP table? MAC of LVS? Or MAC of RealServer?

If the question is will the firewall drop the packet if IP spoofing protection is enabled then I suspect the answer is yes. The reply will come from the real server's MAC address but sourced from the VIP address so I'd recommend disabling any spoofing protection. Hope that helps.
