Hi Siva,
I can ping VIP (IP: 10.10.40.20) from 6500, also from the client-side (IP: 10.10.40.3), but I still can't browse from the VIP for both webservers when I tried http://10.10.40.20 from the client's web browser. I even see reset from the pcap.
I can browse both webservers direct without an issue though.
