Blocking hotspot users between them

RouterOS General
1

I have configured in my WLAN1 the Hotspot, so I don’t want that wireless hotspot users cannot comunicate between them.
I have chosen default forward to NO, but still can communicate.

Have I to do anything more to block communication between hotspot users in wireless interfaces?

Thank you

when setting the default forward to no make sure u do it via a terminal connection and use the set command.
