# Network configuration

This guide covers the network setup required to connect to the CloudQuant Data Liberator platform.

## Firewall requirements

Ensure the following outbound connections are permitted:

| Protocol | Port    | Destination                                   | Purpose                         |
| -------- | ------- | --------------------------------------------- | ------------------------------- |
| HTTPS    | 443     | CloudQuant API endpoints                      | Data queries and authentication |
| TCP      | Various | CloudQuant Data Liberator streaming endpoints | Live data feeds                 |

## Proxy configuration

If your organization uses a proxy server, configure the CloudQuant Data Liberator client accordingly:

<CodeGroup>
  ```python Python theme={null}
  import os
  os.environ['HTTPS_PROXY'] = 'http://your-proxy:8080'
  ```

  ```bash Shell theme={null}
  export HTTPS_PROXY=http://your-proxy:8080
  export NO_PROXY=localhost,127.0.0.1
  ```
</CodeGroup>

## DNS requirements

Ensure your DNS can resolve CloudQuant's service endpoints. Contact CloudQuant support for the current list of required domains.

## Troubleshooting

If you experience connectivity issues:

1. Verify outbound HTTPS (port 443) is open
2. Check proxy settings if applicable
3. Ensure DNS resolution is working
4. Contact [CloudQuant Support](https://www.cloudquant.com/tickets) for endpoint-specific assistance
