Configuring Push Information
This section describes how to configure push information for the data filtering feature.
Context
The FW sends notifications in the text or web page format to users. You can specify the content of the notifications. To modify a notification, export the notification template, edit the notification in the template, and import the template file into the FW.
During data filtering, if the data or application protocol contains the blocked field, the FW pushes a notification page while blocking the data.
In addition, if the HTTP status code of the push information fails to meet your requirement, you can modify the HTTP status code.
- Ensure the security of the file to be imported to prevent pushed pages from containing malicious information such as phishing websites or Trojan horses.
- You can configure push information by using all kinds of HTML tags (including the script), which is risky. Please use it cautiously.
- If the information to be pushed contains Chinese characters, set the coding method to GB2312 between <head> and </head> (for example, <meta http-equiv="Content-Type" content="text/html; charset=GB2312"></meta>) to ensure that the information can be properly displayed.
Procedure
- Choose .
- Optional: Configure the HTTP status code of
the push information.
Select the following status codes and click Apply.
- 401 Unauthorized: Indicates that the request is not authorized.
- 403 Forbidden: Indicates that the server request is denied.
- 404 Not Found: Indicates that the request fails.
- 503 Service Unavailable: Indicates that the server cannot process the request currently.
By default, the HTTP status code of the push information is 503.
- Click Data Filtering Blocking in Data Filtering or click Import and then download the notification template to the local computer.
- Edit the notification content in the template.
<> indicates the Hypertext Markup Language (HTML). Change the content between <> and </>.
In the Data Filtering Blocking notification template, parameter %FILE_NAME indicates the name of a blocked file, and %APP indicates the name of a blocked application. The FW automatically replaces %FILE_NAME and %APP with the actual values when sending notification messages.
- Click Data Filtering Blocking again or Import, click Browse, and then select the edited notification template file.
- Click Import. The new notification takes effect after the template is successfully imported.
Follow-up Procedure
You can perform the following operations to modify notifications or restore default notifications:
Click Export of the notification to be modified to download the notification file. Then edit the downloaded notification and import the file into the FW.
Click Reset corresponding to the notification to be modified to restore the default notification.
If you perform the reset operation in the root system, the root system uses the default notification of the FW.
If you perform the reset operation in the virtual system, the virtual system uses the notification configured in the root system; if the default notification of the root system has not been modified before you perform the reset operation, the virtual system uses the default notification of the FW.
