AIX must not have IP forwarding for IPv6 enabled unless the system is an IPv6 router.

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.

From the command prompt, run the following command:

# /usr/sbin/no -o ip6forwarding ip6forwarding = 0

If the value returned is not "0", this is a finding.

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