Microsoft has announced the public preview of an alternative to Windows VPN that extends corporate security policy protections to mobile devices. Dubbed Microsoft Tunnel Gateway, the new solution is offered as part of Microsoft's cloud-based mobile device management solution, Intune, and will help iOS and Android devices access local resources. Interestingly, the new Tunnel Gateway comes as a Docker container that Microsoft suggests you run on top of one of the supported Linux hosts.
In the rabbit hole
Microsoft explains that they decided to go the container route for the new solution in order to make it easier to maintain. As its name suggests, Tunnel Gateway is designed as a gateway solution for Microsoft Intune, like any other policy-based VPN allowing you to block access to devices that comply with your security policies. Tunnel Gateway runs in a Docker container running on a Linux server that can be physical or virtual on-premises or in the cloud. Tunnel Gateway currently only supports four Linux hosts, including specific versions of Red Hat Enterprise Linux and CentOS, as well as Ubuntu 18.04 and Ubuntu 20.04. Microsoft also suggests processor and memory sizes based on the number of connections you plan to handle. For example, you can support up to a thousand devices on a server with any quad-core processor with 4 GB of RAM and 30 GB of disk space. Once the server is up and running, you can download the Microsoft Tunnel app on your Android and iOS devices from the Google Play Store and Apple App Store, respectively. Via: TechRepublic
