Modifying a Server

Scenario

You can modify the server configuration.

• If you change the local or client CIDR block on the server, clients need to reconnect to the server.
• If you modify advanced settings such as the protocol and port, you need to download the new client configuration file and import it to the clients for the modification to take effect.
