  As your linux-directors are separate machines, you should
not need to add any more addresses to the real-servers.
   
  Please help me with this question 
   
  thanks for your reply horms.But Presently we are using 2 ipaddresses for our real servers one ip with physical networkcard and other one is virtually networkcard adding  to the realserver for hosting websites
   
  ex:- 
eho <ip>
eh1:100 <someip>
   
  In this type of situations also i can use ultramonkey
   
  Thanks for your time

LVS is very efficient.

As your linux-directors are separate machines, you should
not need to add any more addresses to the real-servers.

I would guess that the easiest way to achieve your goals is
to use LVS-NAT, as discussed at:

LVS-DR should also work. But it is a little more tricky to set up.
