This is a very reasonable question coming from many other routers to the mikrotik router.
The long and short of it is that mikrotik provides much more fidelity than your normal consumer router and many soho routers.
To answer your question, note that the NAT menu item is under the FIREWALL menu, not a separate choice.
All my destination NAT rules, where I know (and can limit the source WAN address) who requires access is delineated by the SOURCE ADDRESS LIST (typically more than one user).
Also here (NAT rules) is where you differentiate if the incoming port from the user will actually go to a different server port (translation).
