Piranha load balancing, all requests from client end up with one real server, not load balancing

[Sanjay Mahapatra]

 Hello


 I have a pirahna  load balancer set up with a virtual server /IP that routes UDP  protocol messages  to TWO real server  host-ports. 
  
 One host runs  pirahna and two other hosts act as the  real servers in the is scenario, all three  hosts run on Redhat EL 4 cluster.

  
  The network type is : Direct Routing, and there is no  firewall involved between these hosts.
 

 The  LVS routing table shows both the routes while both  real servers are healthy. 
  
 Problem  :
  
 Even though I have  persistence turned off ( Persistence set to zero seconds ), it appears that all requests  from the same client IP  get  routed to   ONE of the real  servers. I am unable to achieve load distribution  between the two available real servers ( running an automated load test that  originates from a single client IP ) 

I used round robin at first and later used  least connection based scheduling algorithm,  but in each case only one of the real servers appears to receive all messages from the same client.

  
 Is there something I  am missing ? 

Thanks in advance.
