Carp without physical interface IPs

  • I'm doing some reading and it appears that carp is possible these days without requiring the WAN interfaces to have IP addresses assigned at all,  is this possible on pfSense yet?

    It is technically possible to have a CARP VIP and no other IP addresses in that subnet on an interface, but it's not ideal. Only the master node has outbound connectivity so it's difficult to manage packages or updates on the secondary without some extra hoop-jumping.
