Hi!
1. Any particular reason why you need to use NAT for load-balancing on
the same network segment? why not try DR instead?
2. If you really need NAT, you could create a "servers network" (it
doesn't matter if they are on the same network segment, you just need
them to be on different networks, ej. 192.168.1.0/24).
