Summary
The tutorial exclusively demonstrates deploying and testing Azure Firewall DNAT using a Windows Server virtual machine and Remote Desktop (RDP) for connectivity testing. There are no examples or instructions for deploying a Linux VM, nor for testing connectivity using SSH or Linux-native tools. The only operating system mentioned for the workload VM is Windows, and the only connectivity test described is via RDP, a Windows-specific protocol.
Recommendations
  • Add parallel instructions for deploying a Linux virtual machine (e.g., Ubuntu) in the workload subnet.
  • Include steps for testing DNAT access using SSH (port 22) to a Linux VM, alongside or instead of RDP.
  • Provide example NAT rules for both RDP (Windows) and SSH (Linux) scenarios.
  • When listing OS options for the VM, mention both Windows and Linux images, and show how to select either in the portal.
  • Generalize connectivity testing steps to cover both Windows (RDP) and Linux (SSH) use cases, ensuring parity.
  • Where possible, avoid assuming the administrator is using Windows, and provide cross-platform guidance.
