Traffic wroteDNS is :
Protocol UDP
Port 53

yes i known you response but, please open the program http://tunnel.guru/download.php -> protocol dns

the difference is, i select the protocol udp and port 53 (dns) but dont connect.

i select protocol dns and connect correctly (and show the same messages of openvpn) here a pic
