[Envoy] is supported by __Authelia__.
*__Important:__ When using these guides it's important to recognize that we cannot provide a guide for every possible
method of deploying a proxy. These guides show a suggested setup only and you need to understand the proxy
configuration and customize it to your needs. To-that-end we include links to the official proxy documentation
throughout this documentation and in the [See Also](#see-also) section.*
## Get Started
It's __*strongly recommended*__ that users setting up *Authelia* for the first time take a look at our
[Get Started](../prologue/get-started.md) guide. This takes you through various steps which are essential to
bootstrapping *Authelia*.
## Trusted Proxies
*__Important:__ You should read the [Forwarded Headers] section and this section as part of any proxy configuration.
Especially if you have never read it before.*
*__Important:__ The included example is __NOT__ meant for production use. It's used expressly as an example to showcase
how you can configure multiple IP ranges. You should customize this example to fit your specific architecture and needs.
You should only include the specific IP address ranges of the trusted proxies within your architecture and should not
trust entire subnets unless that subnet only has trusted proxies and no other services.*
## Configuration
Below you will find commented examples of the following configuration:
* Authelia Portal
* Protected Endpoint (Nextcloud)
### Theoretical Example
Support for [Envoy] should be possible via [Envoy]'s
[external authorization](https://www.envoyproxy.io/docs/envoy/latest/api-v3/extensions/filters/http/ext_authz/v3/ext_authz.proto.html#extensions-filters-http-ext-authz-v3-extauthz).
