I don't think this is a one-network NAT, as those subnets don't
overlap.  However, I did setup a one-network LVS-NAT just last week that
works fine.  Our private network is a subset of our public network, with
the real servers using the gateway VIP on the directors.  The directors
know nothing of SSH, yet if a client tries to SSH directly to the
private IP of the real server, it succeeds, even though the packets take
a circuitous return trip through the directors.
