2.4 Configuring NAT Settings

You can configure Risk Service to retrieve IP addresses in a NAT environment.

  1. On the Risk Settings page, click Configuration () icon > NAT Settings.

  2. Select Identity Server behind NAT.

  3. In Client IP Header Name, specify the header name of the field to fetch the IP address of a client. For example, X-Forwarded-For.

  4. In Client IP Header Parser, specify the regular expression to retrieve the client’s IP address from the HTTP header value. Header Parser is set as .* by default.

    With the regular expression .* , the rule execution fails even if the client IP address exists in the list of multiple IP addresses. So, if you want to retrieve an IP address from a list of multiple IP addresses, modify the regular expression accordingly.

  5. Click Save.
