Hi,

If you want your VIP to be reachable on the net and you use LVS-DR you
would need 4 public IP addresses :
- VIP
- one for the director
- one for each real server

If you use LVS-NAT and want your VIP to be reachable on the net, you
would need 2 public IP addresses:
- VIP
- one for the director
