WN25-CC-000030 - Windows Server 2025 Internet Protocol version 6 (IPv6) source routing must be configured to the highest protection level to prevent IP source routing.

Information

Configuring the system to disable IPv6 source routing protects against spoofing.

Solution

Configure the policy value for Computer Configuration >> Administrative Templates >> MSS (Legacy) >> MSS: (DisableIPSourceRouting IPv6) IP source routing protection level (protects against packet spoofing) to 'Enabled' with 'Highest protection, source routing is completely disabled' selected.

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.
