      Hello,

      I use CARP with 2 pfsense boxes and my network provider tells me that my network ports announces fancy IP addresses.
      After opening a tcpdump in wireshark, I effectively found wrong addresses (see screenshot attached).

      In the GUI I never configured these adresses.

      Can someone tell me how to stop from announcing theses adresses ?

      Thanks you !

        Somebody correct me if I'm wrong, but CARP uses the same protocol/multicast address(?) as VRRP, but the fields don't match, so those IPs aren't actually announced by CARP but VRRP interprets it that way (and the Wireshark dissector as well).

          The Wireshark dissector is wrong, it doesn't understand CARP.
