Routing Mikrotik how to configure routing?

Question

Computer networks

Good afternoon.
The provider gives 3 "white" addresses. A Mikrotik RB2011iL router is placed on one address. Cash register computers and a server are connected to Mikrotik, to which data from all cash desks is transmitted. Cash desks are placed on 2 other addresses (cash desk1 and cash desk 2). Please tell me how to configure the Mikrotik router so that the cash registers located at the "white" addresses "saw" the server behind the Mikrotik RB2011iL.

Answer 1

You need to forward the port to the server on Mikrotik. You have NAT behind the Mikrotik, and the network is disconnected, so the cash registers will not reach the server directly.

Answer 2

The provider did it. Everything is located in different buildings and on different floors, so the provider installed 2 of its routers. 1st in one building. I selected a port with a white address on it, I hung Mikrotik RB2011iL on it. The 2nd router is in another case - it has allocated 2 ports with white addresses - there are cash registers on them.
