# Running behind a reverse proxy
Running Headscale behind a reverse proxy is suitable for container-based deployments. This is especially useful on a server were port 443 is already being used for other web services.
### Web Sockets
The reverse proxy _must_ be configured to support websockets if you are running headscale 0.17.x+ and tailscale v1.30+.
### 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
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;
map $http_upgrade $connection_upgrade {
default keep-alive;
'websocket' upgrade;
'' close;
}
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;
}
}
```
