# Running headscale behind a reverse proxy
|
|
|
|
Running headscale behind a reverse proxy is useful when running multiple applications on the same server, and you want to reuse the same external IP and port - usually tcp/443 for HTTPS.
|
|
|
|
### WebSockets
|
|
|
|
The reverse proxy MUST be configured to support WebSockets, as it is needed for clients running Tailscale v1.30+.
|
|
|
|
WebSockets support is required when using the headscale embedded DERP server. In this case, you will also need to expose the UDP port used for STUN (by default, udp/3478). Please check our [config-example.yaml](https://github.com/juanfont/headscale/blob/main/config-example.yaml).
|
|
|
|
### TLS
|
|
|
|
Headscale can be configured not to use TLS, leaving it to the reverse proxy to handle. Add the following configuration values to your headscale config file.
|
|
|
|
```yaml
|
|
server_url: https://<YOUR_SERVER_NAME> # This should be the FQDN at which headscale will be served
|
|
listen_addr: 0.0.0.0:8080
|
|
metrics_listen_addr: 0.0.0.0:9090
|
|
tls_cert_path: ""
|
|
tls_key_path: ""
|
|
```
|
|
|
|
## nginx
|
|
|
|
The following example configuration can be used in your nginx setup, substituting values as necessary. `<IP:PORT>` should be the IP address and port where headscale is running. In most cases, this will be `http://localhost:8080`.
|
|
|
|
```Nginx
|
|
map $http_upgrade $connection_upgrade {
|
|
default keep-alive;
|
|
'websocket' upgrade;
|
|
'' close;
|
|
}
|
|
|
|
server {
|
|
listen 80;
|
|
listen [::]:80;
|
|
|
|
listen 443 ssl http2;
|
|
listen [::]:443 ssl http2;
|
|
|
|
server_name <YOUR_SERVER_NAME>;
|
|
|
|
ssl_certificate <PATH_TO_CERT>;
|
|
ssl_certificate_key <PATH_CERT_KEY>;
|
|
ssl_protocols TLSv1.2 TLSv1.3;
|
|
|
|
location / {
|
|
proxy_pass http://<IP:PORT>;
|
|
proxy_http_version 1.1;
|
|
proxy_set_header Upgrade $http_upgrade;
|
|
proxy_set_header Connection $connection_upgrade;
|
|
proxy_set_header Host $server_name;
|
|
proxy_redirect http:// https://;
|
|
proxy_buffering off;
|
|
proxy_set_header X-Real-IP $remote_addr;
|
|
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
|
proxy_set_header X-Forwarded-Proto $http_x_forwarded_proto;
|
|
add_header Strict-Transport-Security "max-age=15552000; includeSubDomains" always;
|
|
}
|
|
}
|
|
```
