 Since Shopware 6.6, the `TRUSTED_PROXIES` environment variable is no longer taken into account out of the box.
-Make sure to create a Symfony configuration to make it configurable again, as shown in the [trusted_env.yaml example](https://github.com/shopware/recipes/blob/main/shopware/docker/0.1/config/packages/trusted_env.yaml).

 For the most part, using Symfony and Varnish doesn't cause any problem.
 But when a request passes through a proxy, certain request information is sent using either the *standard Forwarded* header or *X-Forwarded* headers.
 For example, instead of reading the `REMOTE_ADDR` header (which will now be the IP address of your reverse proxy), the user's true IP will be stored in a standard Forwarded: for="..." header or an *X-Forwarded-For* header.

 The Dockerfile uses the `shopware-cli` image to build the project and then copies the built project into the `base-image` image. The `base-image` is the Shopware Docker image.
