IPv6 Prefixes are not added in IPv6 Firewall Address-list

Hi

We are using Mikrotik software as NAS with external Radius Server. ( PPPoE)

For IPv4 we use address lists provided by external RADIUS Server to stop expired users and redirect them to a web portal.For IPv6 regardless if the prefix comes from local pool or is provided by the External RADIUS Server, the prefixes are not added in the respective ipv6 firewall address-list.

Could anybody let me know – how to create IPv6 Expired users address-list ( which should be provided by external Radius Server ).

Thanks & Regards.
