CARP and WAN DHCP vs Static IPs

  • Hi All,
    We are having a problem with CARP on WAN where the CARP will only fail over all interfaces when the WAN interfaces have a static IP address, otherwise only a single CARP fails.

    Does anyone know (and should it be in the manual) if static IP addresses on WAN interfaces are a requirement for CARP failover to fail all interfaces together?

    Can anyone comment if this is an issue in IPv6?
