Rule for Yandex SmartCaptcha

Set up a rule to redirect requests to SmartCaptcha for verification.

Note

If the Deny action is set for the default basic rule and the requests are sent to SmartCaptcha for verification, add a basic rule that allows requests to the CAPTCHA. The address of the allowed request matches the regular expression: /tmgrdfrend.*. Set the rule to have a higher priority than rules with a CAPTCHA challenge.

Management console
  1. In the management console, select the folder.
  2. Navigate to Smart Web Security.
  3. In the left-hand panel, click Security profiles and select the profile.
  4. Click Add rule and in the window that opens:

    1. Enter a name for the rule, e.g., allow-captcha.

    2. Set Priority higher than that of the rules sending requests to captcha checks.

    3. Enable Only logging.

    4. Specify the rule settings:

      • Type: Base.
      • Action: Allow.
      • Traffic: On condition.
      • Conditions: Request URI.
      • Request path: Matches the regular expression.
      • Enter the /tmgrdfrend.* expression.
    5. Click Add.
