How to set up Mikrotik port forwarding?

Question

Mikrotik

Good afternoon, please tell me the solution in this matter.
There is office A with external ip 96.96.96.96 and office B with external ip 58.58.58.58 , office "A" has a server with a virtual machine, a VPN connection to office "B" is created in this machine. Port forwarding is configured on the virtual machine, and it is possible to go, for example, to this address 96.96.96.96:3389, everything is fine, but when VPN is connected, this option is not available. Since there is a checkbox to use the remote network gateway, you need to configure port forwarding in office "B" and only then will I go to the virtual machine. How to make it so that the VPN is connected and for access from outside use the ip of office "A

"

Answer 1

/ip firewall nat add action=src-nat chain=srcnat dst-port=3389 protocol=tcp dst-address=192.168.88.33 to-addresses=192.168.88.1

where 192.168.88.1 - Mikrotik
192.168.88.33 - PS virtual machine
In a more general case, something like Policy-based Routing would be required https://habr.com/ru/post/101796/

But the problem is that this would have to be configured in a virtual machine, and Windows is too poor an OS for such tricky network tricks.
