You should be able to use the SO_REUSEADDR socket option to bind multiple sockets to the same address. But having said that, you don't want to do this because it's not specified which socket will receive incoming data on that port (you would have to check all sockets for incoming data)

The better option is just to use the same socket to send replies - this can safely be done from multiple threads without any additional synchronisation (as you are using UDP).
