Broadcast UDP message is sent from wrong network interface RRS feed

  • Question

  • I found an issue with sending an UDP message, which looks like a bug, or at least deserves some attention.

    On WinXP SP3 I have two network adapters, configured to have some collision in IPv4 addresses: mask, mask There is a collision but no general networking issues that I am aware of.

    I bind UDP socket to a port on and send broadcast datagram. It appears to be going through adapter It is something I definitely would not expect.

    Some more info here:

    Any comments?
