    No, the cluster cannot force the source IP address of your application's
    outbound UDP traffic to be a cluster virtual IP address. Your application
    must bind specifically to a virtual IP address (as opposed to INADDR_ANY,
    which it is probably binding to right now).

> We have an application that communicates with UDP.  The server is
installed on a cluster and we have two Virtual IP configured.  The firewall
is configured so that communications can only go through one virtual IP
only.  The problem is that when the server replies to the client the source
IP address in the UDP packet is the IP address of one of the NIC cards.  Is
there a way to configure the cluster so that the source IP is always one of
the virtual IP address?
