Firewall Rules

@Handian Sudianto ,

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I understand that you would like to block internet access on an Azure VM except for Microsoft services.

You can leverage Azure Firewall service tags

• You can find a list of all available service tags along with whether or not supported by Firewall here
• For Office 365, see : Use Azure Firewall to protect Office 365

For e.g., you can use "AzurePlatformLKM" tag for Windows licensing or key management service.

Thanks,

Kapil
