real_ip_header

Syntax:	`real_ip_header field \| X-Real-IP \| X-Forwarded-For \| proxy_protocol;`
Default:	`real_ip_header X-Real-IP;`
Context:	`http`, `server`, `location`

Defines the request header field whose value will be used to replace the client address.

The X-Real-IP and X-Forwarded-For parameters may contain an optional port (1.11.0). The address and port should be specified according to RFC 3986.

The proxy_protocol parameter (1.5.12) changes the client address to the one from the PROXY protocol header. The PROXY protocol must be previously enabled by setting the proxy_protocol parameter in the listen directive.
