Updates

NethSecurity allows two types of updates, both available from the Update section under the System menu.

1. Bug & security fixes

These updates are intended for minor updates and bugfixes.

Typically they could be performed automatically, but at any time it is possible to check for new updates available by clicking on Check for Fixes button. These updates do not require a restart of NethSecurity, they are tied to a specific version and distributed using packages.

2. System updates (switching to a different version)

These updates involve the transition to a new version of the firmware that introduces new features, improvements and wider hardware support.

This type of update will reboot the device (which will therefore not be reachable for a few dozen seconds) and then completely rewrites the firmware, preserving all the configurations. However it is recommended to save a configuration backup before proceeding with the upgrade.

If a new version is available, the user interface will display an information banner and a dedicated button Update System that will allow you to perform the update.

Alternatively, it is always possible to manually upload a compatible image using the Update with image file button and proceed with the update.

You can also perform a System update from the command line. To do this, simply save download the new image file (it is recommended to save it inside /tmp directory) and run the following command:

sysupgrade -v nethsecurity-<version>-x86-64-generic-squashfs-combined.img.gz

The sysupgrade command flashes the new image file to the device.

Automatic updates

Subscription required

This feature is available only if the firewall has a valid subscription.

Automatic updates can be enabled from the Update section under the System menu, by enabling the Automatic updates option. Updates are checked daily and, if available, they are automatically downloaded and installed.
