    Carp is flooding my network with VRRP packets (Yes, that doesn't make sense)

      Where was the CARP.pcap capture taken?

      Where was the CARP_Local.pcapng capture taken?

      You can see by the ip.id those packets are duplicated.

      I still suspect something in your switching gear somewhere.

      A comprehensive network diagram is worth 10,000 words and 15 conference calls.
      DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

        You don't happen to run 12 CARP IPs on the same ID do you.

        No, only WAN has the same vhid because of IP Alias(vhid 13).
        All vlan has a different vhid.

        Where was the CARP.pcap capture taken?

        With Pfsense on Management Interface (vhid 4) with Diagnostics -> Packet Capture

        Where was the CARP_Local.pcapng capture taken?

        With my Computer, also in the vhid 4 Network but 4-5 Switchs between Computer and pfsense

        You can see by the ip.id those packets are duplicated.

        Yeah…very special

          Well, I know what it's not… pfSense.

          It's always the switching layer, bro.
