      Hi guys,
      I have pfsense set up as follows:
      WAN - wan interface
      LAN - first lan interface - private subnet 192.168.1.0/24.
      LAN2 - second lan interface private subnet 192.168.2.0/24.

      I have set up NAT so that they can communicate via the internet using routed VIPs.

      I do not want them to be able to communicate with each other though, so I have tried setting the following rule:

      LAN interface - Reject any IPV4 source LAN net destination LAN2 net.

      However when I ping from LAN to LAN2 as follows:
      ping 192.168.2.2

      I still get replies.

      What am I doing wrong?

        Are you letting the ping run or stopping and restarting it?  You need to stop and restart it or clear the existing state.

        DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

          I stopped and restarted the ping and I also rebooted pfsense…

            Ignore my last post.
            I just checked again and I can no longer ping!
