After completing these steps, the selected rule should be deleted, and you can confirm the deletion by checking the firewall rules list again.
Issues with Deleting Firewall Rules
If you encounter issues when trying to delete firewall rules, such as the deleted rules reappearing or the "-" button being grayed out, it could be caused by permission restrictions or third-party security software interfering with the firewall settings.
