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