Prior to making direct edits to the firewall configuration file or changing advanced firewall settings in WHM, a backup of the current configuration should be taken so that the settings can quickly and easily be reverted if needed.

Pre-Flight Check

  • This series assumes you have the ConfigServer Firewall (CSF) installed on your cPanel server, and you have access to WebHost Manager (WHM).
  • If your server currently uses APF but you’d prefer CSF, contact Heroic Support® and request a switch. There is no charge, it typically takes only a few minutes, and the only service that needs to be restarted as a result is the firewall itself. Our support technicians also can port your existing APF rules to CSF. If requesting an upgrade, please be sure to indicate whether your server uses the Guardian backup service so that its rules also can be configured.
