Vulnerability discussion

IP forwarding for IPv6 must not be enabled, as only authorized systems should be permitted to operate as routers.

Check content

To check if IP forwarding is enabled, run the following command: sysctl net.inet6.ip6.forwarding If the values are not '0', this is a finding.

Fix text

To configure the system to disable IP forwarding, add the following line to /etc/sysctl.conf: net.inet6.ip6.forwarding=0

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
