- Example Configuration
- Embedded Variables
ngx_http_realip_module module is used to change the client address and optional port to those sent in the specified header field.
This module is not built by default, it should be enabled with the
--with-http_realip_module configuration parameter.
set_real_ip_from 192.168.1.0/24; set_real_ip_from 192.168.2.1; set_real_ip_from 2001:0db8::/32; real_ip_header X-Forwarded-For; real_ip_recursive on;
Defines trusted addresses that are known to send correct replacement addresses. If the special value
unix: is specified, all UNIX-domain sockets will be trusted. Trusted addresses may also be specified using a hostname (1.13.1).
IPv6 addresses are supported starting from versions 1.3.0 and 1.2.1.
Defines the request header field whose value will be used to replace the client address.
The request header field value that contains an optional port is also used to replace the client port (1.11.0). The address and port should be specified according to RFC 3986.
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.
This directive appeared in versions 1.3.0 and 1.2.1.
If recursive search is disabled, the original client address that matches one of the trusted addresses is replaced by the last address sent in the request header field defined by the real_ip_header directive. If recursive search is enabled, the original client address that matches one of the trusted addresses is replaced by the last non-trusted address sent in the request header field.
- keeps the original client address (1.9.7)
- keeps the original client port (1.11.0)
