1. Create Server Object to Translate (Layer 4 Translation)

   Code Block
   object-group service SERVER_Services tcp port-object eq 3389 port-object eq ident object network SERVER-3389 host 172.32.100.5 nat (inside,outside) static interface service tcp 3389 3389 object network SERVER-ident host 172.32.100.5 nat (inside,outside) static interface service tcp ident ident

2. Create Access List to allow Services to server (Layer 3 Translation)

   Code Block
   access-list outside_access_in extended permit tcp any host SERVER object-group SERVER_Services

Note that the Host is the Server INTERNAL IP. When the Layer 4 is triggered, it will then verify against the access list of the translation. Put simply, by defining the host in the nat object translation, it uses that field as a type of "Private key" that links to the next step in the translation process.
