Title

The system must be configured with a default gateway for IPv6 if the system uses IPv6, unless the system is a router. (Cat II impact)

Discussion

If a system has no default gateway defined, the system is at increased risk of man-in-the-middle, monitoring, and Denial-of-Service attacks.

Check Content

Fix Text

Configure an IPv6 default route on the system.
