Captive portal with AD infra

[vads]

Hello, I'm thinking about enable captive portal but I have some questions. For captive to work my DNS must point to the IP of pfsense, but I have active directory Windows Server 2008 infra and the DNS of the workstations must point to an DNS server, AD or something integrated with AD. How can I solve this problem?

Hi,

Have you tried ?

If this is true (it could be true - just test) :

then this is the show-stopper:

Maybe your portal clients should use the DNS of the pfSense router.
The same question exists for the DHCP server = should it be pfSense, or not ….

The DNS needs to be working. I.e., you must put the IPs into allowed IPs in CP. Doesn't need to be on pfSense at all.
