In VS-NAT the real-servers are on a private network. This really means private.
The only way for packets to get from the real-servers to
outside is to be de-NAT'ed by the director
according to the tables which set up the LVS. Services not under
the control of LVS can be routed normally.

ipvs is a kernel patch. Unfortunately RedHat has prepatched the kernel with
presumably an older version of ipvs. The main effect of this is to cause people
to come up on this list and ask why they can't get their LVS to work. Get a
clean
kernel from www.kernel.org and patch it.

almost everybody who uses RedHat.
