SMB wide open to internet

[Syphonics]

Currently my smb is wide open to the internet, I can simply key in my server up address on file browser and I can access these files ; without VPN connection.

How can I close the smb to the internet and only users whom are connected to the server using VPN and LAN can access these files?
How do I tweak the settings on windows server 2019 firewall

Should at least be Natted through your router. If this a server hosted in a cloud provider? I perimeter firewall will go a long way for securing your network.

The sever is hosted on cloud, what is the settings for the firewall in the cloud?

Depends on the cloud provider
