Question

Computer networks

Good afternoon. There is a network, you need to get access from 192.168.1.2 (PC) to the specified clients, the web-face located behind the router (nat / dhcp). What is the best way to do this?

Answer 1

Or set up routing on Mikrotik
So that the networks know where their neighbors are, the address spaces do not overlap, so everything should work

Answer 2

Forward ports.

Answer 3

Make NAT (most likely it is there) on ubuntu leave the rest on static routing (i.e. remove nat on mikrotik)
