Hi, no because you are in the same subnet. clients within same subnet can communicate directly to each other (the traffic don't route on firewall). I suggest you if you have a layer 3 switch to create acl to block traffic on some ports or mac address (only if the clients are always connected on the same switch ports)

For this you would need to use a Layer 3 switch with Access Control Lists (ACLs) or configure policies at the network switch level to block traffic between specific IP addresses or MAC addresses within the same subnet.

Hello Dear

No, as you're on the same subnet as me. Clients on the same subnet can speak with one another directly; firewalls do not reroute traffic. If you own a layer 3 switch, I advise you to set up an acl to restrict traffic on specific ports or mac addresses (only if the clients are consistently connected on the same switch ports).
