I’m a bit new to Docker, but I’ve installed docker for windows, and got a Node-red container running. In node-red i want to communicate with my PLC by using OPCUA (or MQTT). But when using the OPCUA client it wont connect to my PLC. The PLC is on the same local network as the docker host machine. Same problem with MQTT, but the MQTT broker is in the cloud.
Are there anything I need to do to open up for this type of communication? Or any other ideas for how to fix this?
