Hi all, Just wondering if this may be a bug or just some misconfiguration and someone in the list experienced this before. I’ve got this question from a dual-stack deployment, I will try to summarise it with the info I’ve got (not my deployment, just trying to help). Network using Windows AD and basically only Windows clients. The Windows clients are dual-stack and are authenticated in the AD. The DNS registers correctly both their IPv4 and IPv6 addresses. The Fortinet authenticator is pulling every few seconds via LDAP to the AD in order to “allow” certain groups of users to get access to Internet thru the firewall. The firewall rules are based on the user IPv4 and IPv6 addresses. It seems that this means that because the user has registered initially with IPv6 (as in dual stack takes precedence over IPv4), is reported by the authentication event from the AD to the Fortinet authenticator only the IPv6 address, so it is only gaining access to IPv6. So how you fix this in the authenticator so it gathers both the IPv4 and IPv6 addresses and consequently open the firewall for both IPv4 and IPv6 of this user? Right now it seems the only way to force the authenticator to recognise both the IPv4 and IPv6 addresses of the user is to reautenticate the user with both addresses. It looks to me strange that the authenticator only looks for the “registration event” with a single IP address and not both of them (IPv4 and IPv6, or even multiple IPv6 addresses - like the privacy one). I tried to help looking for Fortinet documents about this, but didn’t found anything relevant. Anyone has seen this behaviour before and/or has any idea about how to fix it?
