How to send a UDP packet on a specific network interface?

Hello,

I don’t find a way to bind outbound udp messages to a specific network interface.
I’m using the java api, with UdpMessage.bind message sent to the manager.
The recieve part is OK though when I send a message using UdpMessage.send, I can’t configure the underlying socket to bind to a network interface.

Thanks,

Regards,

Alexandre
