This is particularly useful when APISIX is behind a reverse proxy since the proxy could act as the request-originating client otherwise. -This is more flexible but functions similarly to Nginx's [ngx_http_realip_module](https://nginx.org/en/docs/http/ngx_http_realip_module.html). +The plugin is functionally similar to NGINX's [ngx_http_realip_module](https://nginx.org/en/docs/http/ngx_http_realip_module.html) but offers more flexibility. -:::info IMPORTANT +## Attributes -This Plugin requires APISIX to run on [APISIX-Runtime](../FAQ.md#how-do-i-build-the-apisix-runtime-environment). +| Name | Type | Required | Valid values | Description | +|-----------|---------|----------|----------------|---------------| +| source | string | Yes | Any Nginx variable like `arg_realip` or `http_x_forwarded_for`. |ically Dynam sets the client's IP address and an optional port, or the client's hostname, from APISIX's view.| +| trusted_addresses | array[string] | No | List of IPs or CIDR ranges. | Dynamically sets the `set_real_ip_from` field. | +| recursive | boolean | No | True to enable, false to disable (default is false) | If the recursive search is disabled, the original client address that matches one of the trusted addresses is replaced by the last address sent in the configured `source`.
