Luiz,

Since CNAT is performing as a router, I don't see how it can talk to two
different overlapping address ranges.   Am I mistaken by what you asked?

If you have two subnets that have overlapping ranges I thought you would do
one of 2 options.   Subnet A gets managed by NetView directly, subnet B
gets addresses changed by CNAT so they are no longer overlapping.   Or,
you could put a CNAT in front of subnet A and a second CNAT in front of
subnet B.   Their NATed networks would not be overlapping in the
configurations.

Kind regards,
