Issue
Follow the instructions in both sections to configure the ESET firewall to function like a new installation.
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.
- Open the main program window of your ESET Windows product.
- Press the F5 key to access Advanced setup.
- Click Network Protection → Firewall and then click the default (
) icon for the section settings you want to revert (Basic in this example). - 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.
