      Hello,

      I installed pfsense for the first time a few days ago. Still learning my way around.

      I've checked the Firewall log a few times after install and all seemed normal. However, after running it for a day I start seeing a "flood" of IPv6 pings, every second, from WAN, with destination being ff02::16. The source address is link local: fe80::213:5fff:fe05:bde2.

      What is going on here? If this is OK, is there a way to not log these specific entries?

      Thanks a lot!
      Dmitri

      Sample of my log below:

        Some more info.

        I enabled DHCP6 on my WAN side, then went to check the interface status. Turns out the IPv6 of fe80::213:5fff:fe05:bde2 is actually my Gateway IPv6.

        Should I allow this traffic to go through from my Gateway IPv6?

        Thanks!
