[KB3323] Restore default settings to the ESET Firewall

Issue

Solution

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.

Export ESET configuration settings using an .xml file.

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

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

  2. Press the F5 key to open Advanced setup.

  3. Click Protections → Network access protection. Expand Firewall and click the Default icon for the section settings you want to revert (In this example, Firewall).

  4.  Click Revert to default.

Revert each section separately 

The settings in each section must be reverted separately. Repeat the steps for each section that requires default settings.
