    Rob,

    In my past setups the VIP was unpingable/reachable
    from the real servers. It could only be accessed from
    the client port of the load balancer.

    To test your vip plug a machine directly into a port
    on the AD3 that iconfigured for client and setup port
    4 for server.

    <snip>
    Port state:
    1: 0.0.0.0, client, server
       filt disabled, filters: empty
    2: 0.0.0.0, server
       filt disabled, filters: empty
    3: 0.0.0.0, server
       filt disabled, filters: empty
    4: 0.0.0.0
       filt disabled, filters: empty
    5: 0.0.0.0, client
       filt disabled, filters: empty
