For Security Reason,
We now only accept Google NTP server connection in Asia.
If you need to use NTP server, you can choose the server in EU/AU/NA/SA/AFR and/or Google Anycast NTP Server(The only server is allowed by DMIT in Asia ):
If you need to use a self-built NTP server, it is recommended to use tunnel protocol or add a non-123 UDP port.
Also, we will drop all the packets which source port is 11211 to our network. There is no limitation on use port 11211 as a server in the DMIT network.
The source port means that when you “downloading”, the server use port 123/11211 sending traffic to your server.
