Restore default settings to the ESET firewall


Follow the instructions in both sections to configure the ESET firewall to function like a new installation.


Revert firewall settings to defaults

Back up your firewall settings

If you have created custom rules or exceptions that allow applications or external devices to run without being blocked by the ESET firewall, we recommend that you record them before restoring default settings. Restoring default settings will delete these rules and exceptions. For instructions to create new exceptions, follow the steps in our Knowledgebase article.

  1. Open the main program window of your ESET Windows product.

  2. Press the F5 key to access Advanced setup.
  3. Click Network Protection → Firewall and then click the default () icon for the section settings you want to revert (Basic in this example).
  4. Click Revert to default

Revert each section separately

The settings in each section have to be reverted separately. Repeat the steps for each section you need to revert to the default settings.
