This may help and suggest starting with Para 6. - https://forum.mikrotik.com/viewtopic.php?t=179343

Do you have an internet service with a ‘real public IP’ that would allow you to port-forward? Or are you double-NAT’d already?

I’m going to guess that you have already tried because you said ‘dont know how to correctly’ but if your ISP doesn’t allow incoming connections (CGNAT) it will never work.
