There is a welcome change coming to the Microsoft Intune Tunnel Gateway server. Soon, Microsoft will increase the number of supported clients per Microsoft Intune Tunnel Gateway server. Currently, only 5000 clients are supported by the Intune Tunnel Gateway server.
20000 (Twenty Thousand) clients will be supported by the Tunnel Gateway server as per Microsoft 365 roadmap item 178921. 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.
With this enhancement in the server’s capacity (20000 clients per server), you can have less server infrastructure in place to support many mobile devices.
Microsoft Tunnel for Microsoft Intune
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.
What is the Challenge with 5000 Clients Support?
The challenge is that you need more server infra to manage if you have more mobile devices using Microsoft Tunnel for Microsoft Intune VPN gateway service.
For example, if you have 20000 mobile devices in this scenario, then you would need 4 Intune Tunnel Gateway servers.
