It is Host-NAT, not NAT.  A host in a private network, when connecting to 
end-hosts outside its realm, could adapt Host Network Address Translation 
to avoid network address translation of end-to-end packets. Such a host
is termed "Host NAT client". 

For details, I suggest, you refer NAR draft by Gabriel or the 
soon-to-be-posted draft-ietf-nat-terminology-01.txt. Thanks.
