VPN Gateway

The documentation for troubleshooting Azure point-to-site VPN connections is heavily Windows-centric. Most troubleshooting steps, error messages, and solutions reference Windows-specific tools (Certificate Manager, mmc.exe, registry edits, Device Manager), PowerShell commands, and Windows file paths. There are no examples or guidance for Linux or macOS VPN clients, nor are equivalent troubleshooting steps provided for non-Windows platforms. This creates friction for users on Linux or macOS, who may encounter similar issues but lack documentation support.

• Add troubleshooting sections for Linux and macOS VPN clients, including common error messages and solutions.
• Provide equivalent commands and file paths for certificate management and VPN configuration on Linux/macOS (e.g., using OpenVPN, NetworkManager, strongSwan, or native tools).
• Include Linux/macOS examples for checking certificate installation, DNS resolution, and network connectivity.
• Where PowerShell or Windows registry edits are mentioned, offer alternative steps for Linux/macOS (such as editing configuration files or using system utilities).
• Clearly indicate which issues are Windows-only and which are cross-platform, to help users quickly identify relevant guidance.

The documentation page demonstrates a notable Windows bias in its Azure CLI instructions, specifically by providing only PowerShell examples for critical configuration steps (such as enabling FastPath and PrivateLinkFastPath on ExpressRoute connections). There are no equivalent Azure CLI (cross-platform) or Bash examples for these operations, and PowerShell commands are presented first and exclusively. This creates friction for Linux/macOS users who may not have access to PowerShell or prefer Bash/CLI workflows.

• Provide Azure CLI (az) command equivalents for all PowerShell-based configuration steps, especially for enabling FastPath and PrivateLinkFastPath on ExpressRoute connections.
• Clearly indicate when a step can be performed in the Azure portal, PowerShell, or CLI, and offer parity in instructions.
• Add notes or links for Linux/macOS users on how to accomplish the same tasks without PowerShell.
• Consider reordering examples so that cross-platform (CLI/portal) instructions are presented before or alongside PowerShell.

The documentation provides critical configuration steps using Azure PowerShell commands, with no equivalent Azure CLI or REST API examples. PowerShell is a Windows-centric tool, and presenting only PowerShell commands creates friction for Linux/macOS users. Additionally, PowerShell instructions are given before mentioning that similar actions can be performed in the Azure portal, reinforcing a Windows-first approach.

• Add Azure CLI examples alongside PowerShell for all command-line configuration steps, especially for enabling FastPath and PrivateLinkFastPath attributes.
• Explicitly mention that all steps can be completed in the Azure portal and provide portal navigation instructions wherever possible.
• Where device configuration examples are given, clarify that syntax may vary by vendor and OS, and provide links or references to Linux-based VPN device documentation if available.
• Consider including REST API equivalents for advanced users on any platform.
