Using MCast with Multiple Network Interfaces

On systems with multiple network interfaces, multicast traffic can be sent or received using any of the available interfaces. By default the system will choose an interface automatically, which might differ from the one you intended to use.

To ensure multicast data is transmitted and received on the desired network, you can explicitly specify the interface the MCast component should use. This is done by setting the SendInterface and ReceiveInterface properties to the IP address of the appropriate network interface:

'Send on this network card 
MCast1.SendInterface = "66.22.44.88"
'Listen on this network card 
MCast1.ReceiveInterface  = "55.22.88.22"
