Then you should be using the NETMAP target.
NETMAP (IPv4-specific)
This target allows you to statically map a whole network of addresses onto another network of addresses. It can
only be used from rules in the nat table.
--to address[/mask]
Network address to map to. The resulting address will be constructed in the following way: All 'one' bits
in the mask are filled in from the new `address'. All bits that are zero in the mask are filled in from
the original address.
