Key Takeaways:
- Microsoft Intune Tunnel Gateway Server
- Upgrade Requirements and Lifecycle Management
- Tunnel Gateway servers must run the latest release or one version behind to remain supported
- Automated upgrade cycles began in May 2026
Let’s discuss about Microsoft Intune Tunnel Gateway Server Scaling Changes to Upgrade Requirements and Lifecycle Management. Microsoft clarified that Intune Tunnel Gateway servers must stay on the latest release (or at most one version behind) to remain supported, with automated upgrade cycles introduced in May 2026. The earlier plan to scale servers to 20,000 clients was cancelled in late 2025.

Microsoft Intune Tunnel Gateway Server Scaling Changes to Upgrade Requirements and Lifecycle Management
Microsoft Tunnel is a VPN gateway solution for Microsoft Intune. This VPN solution is unrelated to Entra solutions such as Global Secure Access and Entra App Proxy. Tunnel Gateway service mainly allows iOS/iPad OS and Android devices to access on-premises resources. It runs in a container on Linux and allows access to on-premises resources from iOS/iPadOS and Android Enterprise devices.
These Linux servers with Docker installed can run either on-premises or in the cloud. Microsoft Tunnel Gateway for Intune installs onto a container that runs on a Linux server, and the management of the Linux server with Docker is Microsoft’s responsibility.

Microsoft Intune Tunnel Gateway Server Lifecycle and Upgrades
Automated upgrade cycles began in May 2026, with servers upgraded one at a time to minimize downtime. Admins can configure upgrades to occur during maintenance windows or allow automatic upgrades. Health check reporting added to flag unsupported server versions.
Practical Impact of Intune Tunnel Gateway Server
Microsoft is still supporting 5000 clients per Tunnel gateway server. Upgrades can disrupt connectivity unless scheduled. Intune now surfaces tunnel server health and upgrade status. Microsoft never published a single “official reason, for the cancellation. Look at the below table.
| Available Reason for Cancellation |
|---|
| Tunnel Gateway is a VPN entry point into corporate networks. Increasing client density per server could amplify the blast radius of outages or vulnerabilities. |
| Microsoft prioritized upgrade compliance and lifecycle management in 2026 to ensure servers stay secure and supported. |
Admin Impact
Organizations still need multiple servers for large deployments. Falling behind more than one version means servers are unsupported. Admins must configure upgrade windows to avoid disruption. Intune health checks now flag unsupported server versions.
2026 shifted the Tunnel Gateway story from scaling ambitions to lifecycle enforcement. Admins must now focus on upgrade compliance, monitoring, and maintenance planning rather than expecting higher client capacity.
