By default, file asset deployment uses port 8810 to send assets from the asset management server to the target. Depending on your environment, you might need to open this port in the target server’s firewall. Alternatively, you can change the port that the connection uses by editing the port property in the agent’s /atg/deployment/file/FileDeploymentServer. If multiple agents run on the same VM, each one’s FileDeploymentServer port must be unique. No corresponding change is required on the asset management server, which detects the port automatically through the RMI connection.
