GEN005610 - The system must not have IP forwarding for IPv6 enabled, unless the system is an IPv6 router.

Information

If the system is configured for IP forwarding and is not a designated router, it could be used to bypass network security by providing a path for communication not filtered by network devices.

Solution

Disable IPv6 forwarding on the system.
# /usr/sbin/no -p -o ip6forwarding=0
