Overview of Microsoft Tunnel​

  • Purpose: Microsoft Tunnel allows Android devices to securely connect to on-premises applications and resources through a VPN, ensuring that sensitive data remains protected.
  • Integration: It integrates with Microsoft 365 and utilizes Azure Active Directory (AAD) for authentication, providing a seamless single sign-on experience.

Key Features and Options​

  2. Always-On VPN:

    • Configuration: You can configure the VPN to maintain a constant connection, ensuring that all traffic is routed through the tunnel without user intervention.

  3. Per-App VPN:

    • Selective Routing: This feature allows you to specify which apps should use the VPN connection, optimizing performance and security by only routing necessary traffic.

  4. Split Tunneling:

    • Traffic Management: You can define which traffic goes through the VPN and which goes directly to the internet, improving efficiency and reducing unnecessary load on the VPN.

  5. Conditional Access:

    • Security Policies: Devices must comply with your organization’s security policies to access the VPN. This includes checks for device compliance and user authentication.

  6. Server Configuration:

    • IP Addressing and DNS: Administrators can configure the IP address range and DNS settings for devices connecting through the tunnel.
    • Port Management: Specify which ports the Tunnel Gateway listens on, ensuring proper communication.
