I just tried your suggestion.... 

I used LocalPort-property to set a fixed port to open a socket for listening
first.

However, any subsequent attempts to use that same port for sending the UDP
packet fail. Only after closing the socket used for listening I can use that
port for sending a packet.

Can you not use the LocalPort property to specify a fixed port?
