Yes, the real servers can work with one NIC. Also, you can try
to hide them. eth0: 192.168.0.2, dummy0: VIP, def gw=192.168.0.1
May be this is working for DR, i.e. without the need for NATing them :)
But they must talk only with VIP through the gateway. You can't
allow traffic with saddr=192.168 to pass the router.
