    It's must go into ports and install it ;))

    cd /usr/ports/net/arping/
    make install clean
    then man arping

    and then read man carp carefully

    there is 2 examples one that work for fail-over and second that make
    fail-over and load-balacing

    i think you should try this one

    <
              ifconfig carp0 create
              ifconfig carp0 vhid 1 pass mekmitasdigoat 192.168.1.10/24
              ifconfig carp1 create
              ifconfig carp1 vhid 2 advskew 100 pass mekmitasdigoat
    192.168.1.10/24

        The configuration for host B is identical, except the advskew is on
    vir-
        tual host 1 rather than virtual host 2.

              ifconfig carp0 create
              ifconfig carp0 vhid 1 advskew 100 pass mekmitasdigoat
    192.168.1.10/24
              ifconfig carp1 create
              ifconfig carp1 vhid 2 pass mekmitasdigoat 192.168.1.10/24

         Finally, the ARP balancing feature must be enabled on both hosts:

              sysctl net.inet.carp.arpbalance=1
    >
    then arping -i em0 192.168.1.10
