Node OS Network Ports
Here are common network ports SolarNode devices rely on, which can be used to configure firewalls if necessary.
For normal operations, SolarNode does not need any inbound connections from the public internet. You might want to configure a firewall/router to forward some ports to SolarNode if you want to be able to remotely manage the node. You can also remotely manage the node without requiring any inbound connections by deploying SolarSSH.
| Ports | Protocol | Description |
|---|---|---|
| 22 | TCP | SSH administration |
| 80, 8080 | TCP | SolarNode web admin GUI |
The following table shows the common network connections made by SolarNode to the public internet. Not all connections are required for normal operations. For example, the HTTP package connections are only required to perform OS package updates, and the MQTT connections are only necessary if SolarNode is configured to post data via MQTT.
