Is the dafault route for the back-end server (johnny) through
the IPVS server (susan). While this is a requirement for
NAT to function correctly, I believe that the version of IPVS
that ships with RH6.2 does not support the router being the
default gateway using direct routing. The problem is that the
return packets from the back-end servers have a source address
of one of the IPVS server's interfaces so it is deemed to be
a spoof and is dropped.
Julian Anastasov was working on a fix to this problem but
I am not sure what the status on this is.
