Hello, I am new to LVS, I am sure same quation might have been asked many times in many different forums and I did search google and red many documents on how to configure LVS-NAT, still I am not able to make it work. Any help would be greatly appriciated. I followed the link http://www.jumpingbean.co.za/linux-cluster-load-balancing-high-availability to configure LVS-NAT to load balance multiple web servers, just to test the basic things I used one load balancer server and one real server and used ipvsadm to configure these servers. With the below configuration I am not able to access the default web page from my real server using http://lb1, when I try to access this page it just hangs and comes back with an error "Internet Explorer cannot display the webpage". After trying to access default web page http://lb1 ipvsadm command showing number of counts under InActConn column eventhough I am not able to access the default web page.
