Hotspot on virtual AP

Hello,
I have a 3 CapAC (RouterBOARD cAP Gi-5acD2nD) configured in WDS.
I have 2 VLANs - VLAN5 and VLAN10
More exactly, the 1st one is wired, and the other 2 are wireless linked between each other.

I’ve setup a virtual AP (GuestAP) on the 2.4GHz network and forced it on VLAN10.

So far so good, clients connecting to the GuestAP are receiving IPs from VLAN10 for a PFSense router.
Now I’m trying to configure a hotspot on that GuestAP only for clients that will connect to that specific SSID and I get and error stating that I cannot configure DHCP server on a slave interface. What does it need a server, since the DHCP server is running on PFSense on my network.

What can I do in this scenario and how can I achieve this goal using WinBox (not good at Mikrotik’s CLI).

Thanks in advance for any help provided.

Hi
you just run Dhcp server of the Vlan interface not Virtual AP
