Mikrotik RB201 forwarding some address

From few weeks I have installed router Mikrotik RB201.
To one port of this router is connected server of terminals.
Now I have blocked all route from this port do Internet except one IP address, where I set in menu

IP - firewall

src. address: x.x.x.x
dst. address: (IP adres in Internet)
src. port: tcp
action: accept

I want to allow connect to another Internet service inserting settings instead IP address - domain address with “https://”.

How and where I can set it?

I don’t know if I understand correctly, but… all filtering is done in the /ip firewall filter menu…
