Hi,
Not necessarily, Nat the host on the inside Only with a manual NAT, put an access list on the DMZ and that should do the trick, for example, host 192.168.10.10 is the host on the inside you want to nat to itself.
object network Inside_server
host 192.168.10.10
nat (inside,dmz) 1 source static Inside_server Inside_server
Put an acl on the DMZ ( If there is one already in, just put a line on it)
access-list dmz-in permit tcp any host 192.168.10.10 eq 3389
access-list dmz-in deny ip any host 192.168.10.10
access-list dmz-in permit ip any any
access-group dmz-in in interface dmz
Hope this helps.
