Now we have the following scenario

  1. Azure domain services
  2. Secure Hub (Third party firewall)
  3. Spoke (workload), a windows server VM

I have added 3389 RDP and 445 Smb to reach my machine (works fine). But the machine cannot reach the Azure Domain services for a Domain join and logon.

What (ports/url) do i need to open to join the server to the Azure domain and logon with Azure credentials? It has to be to be as secure as possible

    Thank you for your question and for reaching out with your question today.
