I’ve got a hotspot running now. And the users on the hotspot can see each other if they use an IP scan or something like that. I want to prevent that users can see each other.
Somebody knows how to block the communication between them?
disable “default forward” on hotspot wlan and add firewall filter rule on forward chain src=hotspot-wlan dst=hotspot-wlan
Can you explain the firewall part a little bit more please?
The “disable default forward” I did now. But in the firewall part is a bit vague.
You said: chain must be on forward. (I did)
But than I must select the hotspot-wlan (my wlan1 I think?) at source. But I can only type an IP address there. Or I have to go to “In. Interface” and “Out. Interface” instead of “src” and “dst”.
Can you please explain the firewall part?
Thanks in advance!
Obviously in interface and out interface 
I selected my Hotspotbridge in the in/out interface. And action drop, and now everyone has still internet/hotspot but they can’t see each other. Ty!
