+#### Microsoft Tunnel support for Red Hat Enterprise Linux 8.6<!-- 14642908  -->
+
+You can now use Red Hat Enterprise Linux (RHEL) 8.6 with [Microsoft Tunnel](../protect/microsoft-tunnel-overview.md). There are no additional requirements beyond those that are needed for RHEL 8.5 support.
+ 
+Like RHEL 8.5, you can use the [readiness tool](../protect/microsoft-tunnel-prerequisites.md#run-the-readiness-tool) (mst-readiness) to check for the presence of the ip_tables module in the Linux kernel. By default, RHEL 8.6 doesn’t load the ip_tables module.
+
+For Linux servers that don't load the module, we've provided [instructions](../protect/microsoft-tunnel-prerequisites.md#manually-load-ip_tables) to load them immediately, and to configure the Linux server to automatically load them at boot.

     These versions of RHEL don't support Docker. Instead, these versions use Podman, and *podman* is part of a module called "container-tools". In this context, a module is a set of RPM packages that represent a component and that usually install together. A typical module contains packages with an application, packages with the application-specific dependency libraries, packages
 with documentation for the application, and packages with helper utilities. For more information, see [Introduction to modules](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/installing_managing_and_removing_user-space_components/introduction-to-modules_using-appstream) in the Red Hat documentation.
