  • Next message: Stanislava Pavlova: "[load balancing] Alteon AD3 gateways problem"

    Wich difference betwen "UDP ena" and "UDP stateless" on virtual server?
    I don't understand these: "Then we also applied a filter that would force
    TCP port 53 requests to a group that had the same servers utilizing the hash
    metric"

    You have the hash metric both group (UDP and TCP)? And what type of filter?

    My configuration (I have two Alteon in Hot-Standby):

    script start "Alteon AD3" 4 /**** DO NOT EDIT THIS LINE!
