Client-Server_Communication
Clients identify the server that manages them by the server’s name or IP address. During the Trend Micro Security server installation, the installer identifies the server computer’s IP addresses, which are then displayed on the Web console’s Client-Server Communication screen.
The server communicates with clients through the listening port, which is port number 61617 by default.
If you change the port number, ensure that it is not currently in use to prevent conflicts with other applications and client-server communication issues.
If a firewall application is in use on the server computer, ensure that the firewall does not block client-server communication through the listening port. For example, if the OfficeScan client firewall has been enabled on the computer, add a policy exception that allows incoming and outgoing traffic through the listening port.
You can configure clients to connect to the server through a proxy server. A proxy server, however, is usually not required for client-server connections within the corporate network.
If you need to configure the server name/IP address, listening port, and proxy server settings, configure them before installing clients. If you have installed clients and then change any of these settings, clients will lose connection with the server and the only way to re-establish connection is to re-deploy the clients.
To configure client-server communication settings:
Administration > Client-Server Communication
Type the server’s name or IP address(es), and listening port.
If there are multiple entries in the Server name (or IP address) field, the client randomly selects an entry. Ensure that client-server connection can be established using all the entries.
Select whether clients connect to the server through a proxy server.
Select the proxy server protocol.
Type the proxy server name or IP address, and port number.
If the proxy server requires authentication, type the user name and password in the fields provided.
Click Save.
If you are prompted to restart Trend Micro Security services for the settings to take effect, perform the following steps:
