No Device & OS Identification in IPv6???

I use the Dynamic Device & OS Identification for addresses and it works great, BUT it only works for IPv4 as far as I can see. You can define an address by MAC address in both IPv4 and IPv6 but you can't create a Dynamic address in IPv6 based on Device or OS. Why is this missing? Its a very helpful feature in IPv4. Is there a workaround?

I'm on 7.4.8

Hi ameif56hgt,

Currently, the dynamic Device & OS Identification feature is not available for IPv6 addresses on FortiGate firewalls, as it relies on protocols associated with IPv4.

Thanks. I kinda figured that, but the question is why? If you click on the dynamic IPv4 address that is created, you get a list of MAC addresses of devices that are matched for that device. Also you can create a IPv6 address composed of a MAC address currently, just like in IPv4, so its seems quite shortsighted that this doesn't work with IPv6. I guess yet another feature that doesn't fully support IPv6.
