Agents identify the server that manages them by the server’s name or IPv4/IPv6 address. During the Trend Micro Security (for Mac) server installation, the installer identifies the server computer’s IP addresses, which are then displayed on the web console’s Agent-Server Communication screen.
The server communicates with agents through the listening port, which is port number 61617 by default.
Notes and reminders:
If you change the port number, ensure that it is not currently in use to prevent conflicts with other applications and agent-server communication issues.
If a firewall application is in use on the server computer, ensure that the firewall does not block agent-server communication through the listening port. For example, if the OfficeScan agent firewall has been enabled on the endpoint, add a policy exception that allows incoming and outgoing traffic through the listening port.
You can configure agents to connect to the server through a proxy server. A proxy server, however, is usually not required for agent-server connections within the corporate network.
If you plan to update or replace all of the existing server names and IPv4/IPv6 addresses or change the listening port or proxy settings, do so before installing agents. If you have installed agents and then make changes, agents will lose connection with the server and the only way to re-establish connection is to re-deploy the agents.
If there are multiple entries in the Server name (or IP address) field, the agent randomly selects an entry. Ensure that agent-server connection can be established using all the entries.
