Http client nat to lan - Advice

[Summer]

Dear Sirs,

I need an advice if it is possible to achieve this:

internet      >   pfsense              >  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

HAProxy 1.7 stable was just released so you might want to try the 1.7 Dev package with the hope that it will be upgraded to stable soon enough.
