Blocking access between clients by ip

RouterOS Beginner Basics

Hi there
I’ve got a hotspot setup but I’m trying to block access between my switch and the clients connected to it.

My switch has an IP address of 10.5.50.2 and clients have anything between 10.5.50.3-255.

I’ve create a drop rule but it does not seem to be picking up any traffic. At its placed right on the top of the firewall rules.

Chain=forward src.add=10.5.50.0/24 dst.add=10.5.50.0/24 action=drop

I should mention that the switch is on bridge interface with a few ports.
