Access IP Address Via Wifi

Dear forum,

I have a question, how do I configure the mikrotik so that I can access a computer in this case server IP via wifi.
The topology is as follows :
Internet → wifi → router → switch → computer 1, computer 2, etc.
Now I want to access for example computer 1 via wifi, how can I do that and how do I configure the mikrotik

Many thanks & best regards
Michael Reno

What device is holding your wifi AP?
Where is the device connecting from located? At the same wifi or on the internet somewhere?

I don’t use any wifi AP, I directly connect to the wifi
