Hello,

I'm trying to do load balancing of incoming traffic to my applications. This applications are not very  smp friendly, and I want try to run some instances according to number of cpus on single machine. And balance load of incoming traffic/connections to this applications.
Looks like is should be similar to http://www.austintek.com/LVS/LVS-HOWTO/HOWTO/LVS-HOWTO.localnode.html

 linux kernel 2.6.32 with  or without hide interface patches.  Tried different configurations but could not see packets on application layer.

192.168.1.165 - eth0 - interface for external connections
195.0.0.1 - dummy0 - virtual interface, real application is binded to that address.

Configuration is:
-A -t 192.168.1.165:1234 -s wlc
-a -t 192.168.1.165:1234 -r 195.0.0.1:1234 -g -w

#ipvsadm -L -n
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
TCP  192.168.1.165:1234 wlc
  -> 195.0.0.1:1234               Local   1      0          0

As the result, server application does receive anything on accept(). I tried to make dummy0 a hidden device and play with arp settings. But without result.

I will be happy to hear any idea how to do connection in this environment.
