With LVS-DR you only need one interface. The VIP is an ip resource that is
"in use" by the active LVS box. Since ip traffic is generally a public
service like www it is very very common for the VIP to be a public IP. Hope
that helps.
The setup you seem to consistently describe is LVS-NAT. Please checkout
http://www.linuxvirtualserver.org/how.html carefully and write back with any
questions.
good luck,
