WN11-CC-000030 - The system must be configured to prevent Internet Control Message Protocol (ICMP) redirects from overriding Open Shortest Path First (OSPF) generated routes.

Information

Allowing ICMP redirect of routes can lead to traffic not being routed properly. When disabled, this forces ICMP to be routed via shortest path first.

Solution

Configure the policy value for Computer Configuration >> Administrative Templates >> MSS (Legacy) >> 'MSS: (EnableICMPRedirect) Allow ICMP redirects to override OSPF generated routes' to 'Disabled'.

This policy setting requires the installation of the MSS-Legacy custom templates included with the STIG package. 'MSS-Legacy.admx' and 'MSS-Legacy.adml' must be copied to the \Windows\PolicyDefinitions and \Windows\PolicyDefinitions\en-US directories respectively.
