UdpDiscoveryEndpoint with a broadcast address

Question

Is it possible to use Wcf UdpDiscoveryEndpoint with a broadcast address instead of multicast ? I tried using a broadcast address but that threw an exception, is it a limitation of WcfDiscovery ?

this is the exception:

System.Net.Sockets.SocketException (0x80004005): The requested address is not valid in its context

I have had the same problem at a customer's server. It turned out that he had two network devices with overlapping subnet masks configured. Thus udpDiscoveryEndpoint could not start listening with the above exception.
