Dear Sirs,
I need an advice is it possible to achieve this:

internet      >   mikrotik              >  lan 
client               nat http                   multiple internal http server
                       from  80 to  80 of:   192.168.1.1 for client 1   
                                                      192.168.1.2 for client 2
                                                      192.168.1.3 for client 3

can the client from the internet be allowed to access only the corresponding internal server i.e. client1 can connect only to 192.168.1.1?

How can I knwo who is the client from the internet?

I cannot use vpn. Only http.

Kindly ask your where to look to start searching documentation.
Thanks, BR

If they have different known ip addresses you can else it is not easy. Else you can use different ports redirect on the wan port
