Publishing 2 or more web servers?

Question

Computer networks

Tell me, in my network there are 2 web servers and 1 router, is it possible to publish both of these servers outside, without using different ports?
Those. for example, if a user from an external network enters site1.ru, the router sends a request to server1, and if I go to site2.ru, it sends it to server2.
The router is Mikrotik.
There is a possibility to install other servers or software.
