Wizards > Application Firewall Wizard

The Application Firewall wizard provides safe configuration for many common use cases, but not for everything. If at any time during the wizard you are unable to find the options that you need, you can click Cancel and proceed using manual configuration. See the “Manual Configuration Procedure” .

The screen displayed here will vary depending on your choice of policy rule in the previous step. For the following policy rules, the wizard displays the Set Application Firewall Object Content screen on which you can select the traffic direction to scan, and the content or keywords to match.

If you selected a choice with the words except the ones specified in the previous step, content that you enter here will be the only content that does not cause the action to occur. See “Negative Matching” .
In the Content text box, type or paste a text or hexadecimal representation of the content to match, and then click Add . Repeat until all content is added to the List text box.
Click Next .

If you selected a policy type in the previous step that did not result in the Set Application Firewall Object Content screen with the standard options, the wizard displays a screen that allows you to select the traffic direction, and certain other choices depending on the policy type.

Click Next .
