### Enable Proxy Forwarded Headers { #enable-proxy-forwarded-headers }

You can start FastAPI CLI with the *CLI Option* `--forwarded-allow-ips` and pass the IP addresses that should be trusted to read those forwarded headers.

If you set it to `--forwarded-allow-ips="*"` it would trust all the incoming IPs.

* `allow_origin_regex` - A regex string to match against origins that should be permitted to make cross-origin requests. e.g. `'https://.*\.example\.org'`.
* `allow_methods` - A list of HTTP methods that should be allowed for cross-origin requests. Defaults to `['GET']`. You can use `['*']` to allow all standard methods.

### Ativar headers encaminhados pelo proxy { #enable-proxy-forwarded-headers }

Você pode iniciar a CLI do FastAPI com a opção de linha de comando `--forwarded-allow-ips` e informar os endereços IP que devem ser confiáveis para ler esses headers encaminhados.

Se você definir como `--forwarded-allow-ips="*"`, ele confiará em todos os IPs de entrada.

///

### Включить пересылаемые заголовки прокси { #enable-proxy-forwarded-headers }

Вы можете запустить FastAPI CLI с опцией командной строки `--forwarded-allow-ips` и передать IP‑адреса, которым следует доверять при чтении этих пересылаемых заголовков.

Если указать `--forwarded-allow-ips="*"`, приложение будет доверять всем входящим IP.

### Habilitar headers reenviados por el Proxy { #enable-proxy-forwarded-headers }

Puedes iniciar FastAPI CLI con la *Opción de CLI* `--forwarded-allow-ips` y pasar las direcciones IP que deberían ser confiables para leer esos headers reenviados.

Si lo estableces a `--forwarded-allow-ips="*"`, confiaría en todas las IPs entrantes.
