Hi, I have exactly the same problem as you. Did you do any progress with this problem?
I have some simple results of my experiments with this problem. When one connection between server and client is established and other client tries to connect, then SSL_read(ssl_01) returns error: SSL_ERROR_WANT_READ. But when I try to accept this attempt with SSL_accept(ssl_02), then this function call fails and returns error: SSL_ERROR_SSL. I hope it will not be necessary to have extra socket for every DTLS connection. Any documentation for using DTLS with OpenSSL library is really missing.
