“Auto update” feature of WFilter NG firewall can upgrade “protocol pattern database” and “url category database” automatically. By default, WFilter NG firewall has “auto update” enabled.
However, “auto update” can not perform fireware upgrade. When a new version comes out, you need to manually perform the system fireware upgrade.
This guide demonstrates the steps to perform a fireware upgrade of WFilter NG firewall.
1. Make a backup of current settings.
Please note that upgrade may fail on power supply issue, disk issue… So at first, please export current settings to a backup file in “Config”->”Backup”. In case when you’re unlucky, you don’t need to re-configure the whole system.
2. Click “Check Update now”.
3. Found a new version, then click “Upgrade”.
4. Downloading the new firmware.
At lease one reboot is required during the upgrading. All settings and data will persist after the upgrading.
