Note: This web page is controlled by the Security Profiles field in the Personal Firewall Basic Configuration page. If a fixed profile (without the word 'Custom' in the name) is selected, this web page is read-only and no configuration change is allowed. The Edit column, "Apply", "Add Rule" and "Purge Table" buttons are removed. If a custom profile is selected, configuration change is allowed on this web page.
