vaultwarden/Proxy-examples.md

In this document, `<SERVER>` refers to the IP or domain where you access Vaultwarden. If both the reverse proxy and Vaultwarden are running on the same system, simply use `localhost`.

By default, Vaultwarden listens on port 80 for web (REST API) traffic and [[WebSocket traffic|Enabling-WebSocket-notifications]].
The reverse proxy should be configured to terminate SSL/TLS connections (preferably on port 443, the standard port for HTTPS). The reverse proxy then passes incoming client requests to Vaultwarden on port 80 or the port on which you configured Vaultwarden to listen on, and upon receiving a response from Vaultwarden, passes that response back to the client.

Note that when you put Vaultwarden behind a reverse proxy, the connections between the reverse proxy and Vaultwarden are typically assumed to be going through a secure private network, and thus do not need to be encrypted. The examples below assume you are running in this configuration, in which case you should not enable the HTTPS functionality built into Vaultwarden (i.e., you should not set the `ROCKET_TLS` environment variable). If you do, connections will fail since the reverse proxy is using HTTP to connect to Vaultwarden, but you're configuring Vaultwarden to expect HTTPS.

It's common to use [Docker Compose](https://docs.docker.com/compose/) to link containerized services together (e.g., Vaultwarden and a reverse proxy). See [[Using Docker Compose|Using-Docker-Compose]] for an example of this.

Secure TLS protocol and cipher configurations for webservers can be generated using Mozilla's [SSL Configuration Generator](https://ssl-config.mozilla.org/). All supported browsers and the Mobile apps are known to work with the "Modern" configuration.

<summary>Caddy 2.x</summary><br/>

Caddy 2 will automatically enable HTTPS in most circumstances, check the [docs](https://caddyserver.com/docs/automatic-https#activation).

In the Caddyfile syntax, `{$VAR}` denotes the value of the environment variable `VAR`.
If you prefer, you can also directly specify a value instead of substituting an env var value.

<summary>lighttpd with sub-path (by FlakyPi)</summary><br/>

In this example Vaultwarden will be available via https://vaultwarden.example.tld/vault/<br/>
If you want to use any other sub-path, like `bitwarden` or `secret-vault` you should change `vault` in the example below to match.<br/>

```lighttpd
server.modules += (
"mod_openssl"
)

$SERVER["socket"] == ":443" {  
    ssl.engine   = "enable"   
    ssl.pemfile  = "/etc/letsencrypt/live/vaultwarden.example.tld/fullchain.pem"
    ssl.privkey  = "/etc/letsencrypt/live/vaultwarden.example.tld/privkey.pem"
}

# Redirect HTTP requests (port 80) to HTTPS (port 443)
$SERVER["socket"] == ":80" {  
        $HTTP["host"] =~ "vaultwarden.example.tld" {  
         url.redirect = ( "^/(.*)" => "https://vaultwarden.example.tld/$1" )  
          server.name                 = "vaultwarden.example.tld"   
        }  
}

server.modules += ( "mod_proxy" )

$HTTP["host"] == "vaultwarden.example.tld" {
    $HTTP["url"] =~ "/vault" {
       proxy.server  = ( "" => ("vaultwarden" => ( "host" => "<SERVER>", "port" => 8080 )))
       proxy.forwarded = ( "for" => 1 )
       proxy.header = (
           "https-remap" => "enable",
           "upgrade" => "enable",
           "connect" => "enable"
       )
    }
}
```
You'll have to set `IP_HEADER` to `X-Forwarded-For` instead of `X-Real-IP` in the Vaultwarden environment.

If you run into 504 Gateway Timeout problems, tell nginx to wait longer for Vaultwarden by adding longer timeouts to the `server {` section, for example:

```nginx
  proxy_connect_timeout       777;
  proxy_send_timeout          777;
  proxy_read_timeout          777;
  send_timeout                777;

<summary>Nginx with sub-path (by <a href="https://github.com/BlackDex" target="_blank">@BlackDex</a>)</summary><br/>

If you want to use any other sub-path, like `bitwarden` or `secret-vault` you should change `/vault/` in the example below to match.<br/>

<summary>Nginx with proxy_protocol in front (by dionysius)</summary><br/>

In this example there is a downstream proxy communicating in [proxy_protocol in front of this nginx](https://docs.nginx.com/nginx/admin-guide/load-balancer/using-proxy-protocol/) (E.g. a [LXD proxy device with proxy_protocol enabled](https://linuxcontainers.org/lxd/docs/master/reference/devices_proxy/)). Nginx needs to correctly consume the protocol and headers to forward need to be set from the those. Lines marked with `# <---` have different contents than BlackDex's example.

For reference this LXD downstream proxy device configuration:
```yaml
devices:
  http:
    connect: tcp:[::1]:80
    listen: tcp:[::]:80
    proxy_protocol: "true"
    type: proxy
  https:
    connect: tcp:[::1]:443
    listen: tcp:[::]:443
    proxy_protocol: "true"
    type: proxy
```

```nginx
# proxy_protocol related:

set_real_ip_from ::1; # which downstream proxy to trust, enter address of your proxy in front
real_ip_header proxy_protocol; # optional, if you want nginx to override remote_addr with info from proxy_protocol. depends on which variables you use regarding remote addr in log template and in server or stream blocks.

Ensure you have the websocket proxy module loaded somewhere in your apache config.

```
LoadModule proxy_wstunnel_module modules/mod_proxy_wstunnel.so`
