      I'm using the default pfSense firewall rules, have full internet connectivity on all my machines, and am very happy with the way pfSense is performing, but have a question about ICMP communication between the router and pfSense firewall behind it.

      The setup is router -> pfSense -> switch -> machines and I can connect to the net and to the firewall GUI without any problem.

      From pftop:

      
      PR     D  SRC           DEST         STATE    AGE      EXP      PKTS    BYTES
      
      ICMP   0  Firewall      Router       0:0      32033    10       63996   4001k
      
      

      I take it this is just the firewall pinging the router and it responding, but should it be doing this continuously? I had to reboot last night due to an unrelated issue and it holds this state as long as it's up, both now and before I rebooted.

      It's not a drain on resources or anything, I was just wondering if this was normal behavior or something that needed tweaking. TIA

      Edit: The default router rule was not to respond to ping. I set it to respond to ping to see it if would release it but that doesn't seem to be the case. I can't make a specific rule for the firewall and would rather not have it respond to ping if I could get around it.

        That's for the quality graph and determining gateway accessibility. You can turn off monitoring on the gateway if you don't need those.

          It's not hurting anything so I'll just leave it as is for the graph.

          Thanks a lot.
