IPSetForwardedIPConfig
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, Amazon WAF doesn't apply the rule to the web request at all.
This configuration is used only for IPSetReferenceStatement. For GeoMatchStatement and RateBasedStatement, use ForwardedIPConfig instead.

You can specify the following fallback behaviors:
-
MATCH
- Treat the web request as matching the rule statement. Amazon WAF applies the rule action to the request. -

- Position
-
The position in the header to search for the IP address. The header can contain IP addresses of the original client and also of proxies. For example, the header value could be
10.1.1.1, 127.0.0.0, 10.10.10.10
where the first IP address identifies the original client and the rest identify proxies that the request went through.The options for this setting are the following:
-
FIRST - Inspect the first IP address in the list of IP addresses in the header. This is usually the client's original IP.
-
LAST - Inspect the last IP address in the list of IP addresses in the header.
-
ANY - Inspect all IP addresses in the header for a match. If the header contains more than 10 IP addresses, Amazon WAF inspects the last 10.

FIRST | LAST | ANY
