I believe the answer is maybe.  As I understand LVS-DR, the director  
needs to be on the same layer2 segment as the real servers in some way.  
This is because it must do an ARP lookup of their hardware addresses,  
and then send packets directly to those hardware addresses. This is why  
LVS-TUN exists.
