Description
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.
ℹ️ Check
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.
✔️ Fix
Disable IPv6 forwarding on the system:
# /usr/sbin/no -p -o ip6forwarding=0
