Security Agents identify the server that manages them by the server’s name or IPv4/IPv6 address. During the Apex One (Mac) server installation, the installer identifies the server computer’s IP addresses, which are then displayed on the Agent-Server Communication screen.
The server communicates with Security Agents 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 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 Apex One Security 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 Security 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 Security Agents. If you have installed Security Agents and then make changes, Security Agents will lose connection with the server and the only way to re-establish connection is to re-deploy the Security Agents.
