[Traefik] is a reverse proxy 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.*
## Requirements
You need the following to run __Authelia__ with [Traefik]:
* [Traefik] [v2.0.0](https://github.com/traefik/traefik/releases/tag/v2.0.0) or greater
(a guide exists for 1.x [here](traefikv1.md))
* [Traefik] [v2.4.1](https://github.com/traefik/traefik/releases/tag/v2.4.1) or greater if you wish to use
[basic authentication](#basic-authentication)
## 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.*
[Traefik] by default doesn't trust any other proxies requiring explicit configuration of which proxies are trusted
and removes potentially fabricated headers that are likely to lead to security issues, and it is difficult to configure
this incorrectly. This is an important security feature that is common with proxies with good security practices.
In the example we have four commented lines which configure `trustedIPs` which show an example on adding the following
networks to the trusted proxy list in [Traefik]:
* 10.0.0.0/8
* 172.16.0.0/16
* 192.168.0.0/16
* fc00::/7
See the [Entry Points](https://doc.traefik.io/traefik/routing/entrypoints) documentation for more information.
## Configuration
Below you will find commented examples of the following docker deployment:
* [Traefik]
* Authelia portal
* Protected endpoint (Nextcloud)
* Protected endpoint with [Authorization] header for basic authentication (Heimdall)
The below configuration looks to provide examples of running [Traefik] 2.x with labels to protect your endpoint
(Nextcloud in this case).
Please ensure that you also setup the respective [ACME configuration](https://docs.traefik.io/https/acme/) for your
[Traefik] setup as this is not covered in the example below.
### Docker Compose
This is an example configuration using [docker compose] labels:

### YAML
This example uses a `docker-compose.yml` similar to the one above however it has two major differences:
1. A majority of the configuration is in YAML instead of the `labels` section of the `docker-compose.yml` file.
2. It connects to __Authelia__ over TLS with client certificates which ensures that [Traefik] is a proxy
authorized to communicate with __Authelia__. This expects that the
[Server TLS](../../configuration/miscellaneous/server.md#tls) section is configured correctly.
* The client certificates can easily be disabled by commenting the `cert` and `key` options in the `http.middlewares`
section for the `forwardAuth` middlewares and the `certificates` in the `http.serversTransports` section.
* The TLS communication can be disabled by commenting the entire `tls` section in the `http.middlewares` section for
all `forwardAuth` middlewares, adjusting the `authelia` router in the `http.routers` section to use the
`authelia-net@docker` service, and commenting the `authelia` service in the `http.service` section.

## FAQ
### Basic Authentication
Authelia provides the means to be able to authenticate your first factor via the [Proxy-Authorization] header, this
is compatible with [Traefik].
If you have a use-case which requires the use of the [Authorization] header/basic authentication login prompt you can
call Authelia's `/api/verify?auth=basic` endpoint to force a switch to the [Authorization] header.
### Middleware authelia@docker not found
If [Traefik] and __Authelia__ are defined in different docker compose stacks you may experience an issue where [Traefik]
complains that: `middleware authelia@docker not found`.
This can be avoided a couple different ways:
1. Ensure __Authelia__ container is up before [Traefik] is started:
* Utilise the [depends_on](https://docs.docker.com/compose/compose-file/#depends_on) option
2. Define the __Authelia__ middleware on your [Traefik] container. See the below example.
```yaml
- 'traefik.http.middlewares.authelia.forwardAuth.address=http://authelia:9091/api/verify?rd=https%3A%2F%2Fauth.example.com%2F'
- 'traefik.http.middlewares.authelia.forwardAuth.trustForwardHeader=true'
- 'traefik.http.middlewares.authelia.forwardAuth.authResponseHeaders=Remote-User,Remote-Groups,Remote-Name,Remote-Email'
```
