Firewall tab

When configured, the Nodegrid device functions as a Firewall. There are six built-in default chains (three for IPv4, three for IPv6). These accept packets (Output, Input, and Forward). As needed, additional user chains can be created. (Default chains cannot be deleted.)

The Nodegrid platform comes with its own firewall which is based on iptables. The WebUI and the CLI provide an easy way of creating and managing the firewall. By default, the firewall accepts all incoming traffic. Specifically, if the Nodegrid is exposed to an internet connection either directly or indirectly is it recommended to secure the Nodegrid with a valid firewall configuration.
