In the actual keepalived release the kernel 2.4 SNAT is not supported. I 
will be supported in he next release. When a realserver is down keepalived 
send o the kernel two thinks : 1. An ipvs cmd to remove he realserver from 
the server pool (same as ipvsadm) 2. An ipfw cmd to remove the realserver 
from he NAT table (same as ipchains). If you want more than one VIP on the 
same NIC you should add an ipalias to your NIC and add an iptable SNAT rule 
=> This will be automaticaly done in the next keepalived release.
Best regards,
