      Hey guys,

      I have been facing some issues related to the firewall rule on Pfsense.

      I have my LAN Network 192.168.0.0/23, I am looking to block ICMP request from my Laptop IP 192.168.0.205 to the Chromecast IP 192.168.1.219.

      I created a rule to block the ICMP echo request but it seems not working. I can still ping the chromecast from my Laptop. I tried killing the states but it didn't resolve my issue.

      Please correct me if I am doing something wrong here/

        @qaiserajaz You're using a /23 mask which makes 192.168.0.x and 192.168.1.x part of the same subnet. This means that traffic between you rPC and Chromecast won't even hit the firewall. Btw, your three LAN rules under the block rule are redundant by the Allow All rule at the bottom.

          Thanks a lot for your response.

          I am not really good at the firewall and I wanted to know if I want to block the communication between my PC and Chromecast, what should be the best approach?

          Currently, my DHCP is the Pfsense itself with the subnet /23 and the gateway is also pfsense.

          By looking at your response, I assume that the communication can't be blocked if the IPs are on the same subnet?

            Correct.

            if I want to block the communication between my PC and Chromecast, what should be the best approach?

            Put them on different networks.

              @kom Thanks for the help.

              I put my chromecast on a different Vlan and blocked the access.
