+#### Microsoft Tunnel support for Red Hat Enterprise Linux 8.5<!-- 13182253  -->
+
+You can now use Red Hat Enterprise Linux (RHEL) 8.5 with [Microsoft Tunnel](../protect/microsoft-tunnel-overview.md).
+
+To support RHEL 8.5, we’ve also updated the [readiness tool](../protect/microsoft-tunnel-prerequisites.md#run-the-readiness-tool) (mst-readiness) with a new check for the presence of the ip_tables module in the Linux kernel. By default, RHEL 8.5 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.
