I had a similar problem with LVS_NAT, and it had nothing to do with the
kernel version.

I was using the redirector also as the gateway. When I swapped the VIPs of
my directors, I forgot to swap the internal gateway IP's so the new
director was not the gateway, like the old one had been, for the
realservers. Where was my gateway? I had turned it off (for testing
failover)! Making the new director takeover the gateway IP too got things
going again.
