In Kernels up to 2.6.10 you can add several --to-destination options. For
those kernels, if you specify more than one destination address, either via an
address range or multiple --to-destination options, a simple round-robin (one
after another in cycle) load balancing takes place between these addresses.
Later Kernels (>= 2.6.11-rc1) don't have the ability to NAT to multiple ranges
anymore.
