 I'm playing with LVS, but no way to redirect HTTP request to real
   servers (details on http://pastebin.com/LUFRefnq).
   Some TCP 80 packets arrives to real servers, but looks like replies not.
   Any simple example of LVS?
   Should I 'echo 1 > /proc/sys/net/ipv4/ip_forward' in any server?
   Thanks
