Publish Telemt's container metrics port 9090 as 192.168.0.35:9092 because Cockpit already owns host port 9090. Bind the application listener to 0.0.0.0 inside the container and restrict Telemt's metrics whitelist to the client-02 Zabbix server at 192.168.0.34/32.\n\nDocument the Zabbix template macro URL and the Telemt 3.4.25 loopback-binding gotcha. The live endpoint returned HTTP 200 with 40,235 bytes from the Zabbix server; Telemt remained healthy and rebuilt its Telegram DC connections in six seconds.
