FortiOS 5.0 fully supports flow-based inspection of IPv6 traffic. This includes full support for IPS, application control, as well as flow-based virus scanning, and web filtering.

To add flow-based inspection to IPv6 traffic go to Policy > Policy > IPv6 Policy and select Create New to add an IPv6 Security Policy. Configure the policy to accept the traffic to be scanned. Select UTM and select the UTM profiles to apply to the traffic. To apply flow‑based inspection you can select an IPS and an application control profile. You can also select antivirus or web filtering profiles in which flow-based inspection has been selected.
