    Tristano,

    There is a setting under /c/slb/group x called viphlth. By changing this
    setting, the switch will send the health checks to each real server using
    the Destination IP address of the VIP.

    Hi Ken,
    Yes, I enabled nonat on the service and submac on the real servers, but
    even the health checks are directed to the real servers' addresses
    instead of the VIP.

    Thank you

    Tristano,

       Did you remember to enable nonat on the service? So
    it would not do the VIP to RIP NAT?

    Regards,

    Ken T.
