  3. Hi,

    I want to configure the zen laod balancer as per the scenario. I have two webservers.

    webserver1.mydomain.com – both public and priate ip address with nating
    webserver1.mydomain.com – both public and priate ip address with nating
    webserver.mydomain.com – public request hits here. (virtual ip for both webservers)

    How to configre the above in the zen.

    Thanks in advance.

    Ashok
