I don't believe that this is possible.  You must map the address to one
single other address, or not map at all.  You cannot map to two
different IP addresses.

Your best bet is to put an IP alias/secondary IP address on the server,
and nat to that with the old 192.168.1.1 address during transition.

Thanks,
