# License Server (Deprecated)

{% hint style="warning" %}
The License Server is deprecated. New deployments should use [Secure Gateway](/deploy/enterprise-deployment/secure-gateway.md), its successor, which adds local caching of model weights and container images.
{% endhint %}

## Prerequisites

* Linux server running Ubuntu 20.04+ or Debian 11+
* Internet access to api.roboflow\.com and repo.roboflow\.com
* Static IP address or hostname
* Port 80 available (or custom port)
* Docker Engine 20.10+
* 200GB+ storage
* 4GB+ memory

## Using the License Server

If you wish to firewall the Roboflow Inference Server from the Internet, you will need to use the Roboflow License Server which acts as a proxy for the Roboflow API and your models' weights.

On a machine with access to `https://api.roboflow.com` and `https://repo.roboflow.com` (and port `80` open to the Inference Server running in your private network), pull the License Server Docker container:

```
docker pull repo.roboflow.com/roboflow/license-server
```

And run it:

```
docker run -d --name license-server -p 80:80 --restart unless-stopped \
    repo.roboflow.com/roboflow/license-server:latest
```

Configure your Inference Server to use this License Server by passing its IP in the `LICENSE_SERVER` environment variable:

```
sudo docker run --net=host --env LICENSE_SERVER=10.0.1.1 roboflow/inference-server:cpu
```

## Configuring via Device Manager

If you manage your devices through [Device Manager](/deploy/device-manager.md), you can set the License Server address directly in the Configuration tab for each device's inference service.

When you enter a License Server address, `API_BASE_URL` is automatically set to `https://api.roboflow.com`. This gives the License Server an upstream to proxy requests to, and prevents a misconfiguration where both `LICENSE_SERVER` and `API_BASE_URL` point to the same on-prem address (which would cause a recursive proxy loop).

Clearing the License Server field does not remove `API_BASE_URL`, so existing configurations are not disrupted.
