# Offline and air-gapped

Running the gateway without internet access.

The gateway is built to run where nothing may call out. Two kinds of outbound traffic exist: calls the organisation chooses (to model providers and tool servers) and calls the software makes on its own. The second kind is switched off.

| Component         | Calls out on its own                  | How it is switched off                                                          |
| ----------------- | ------------------------------------- | ------------------------------------------------------------------------------- |
| LLM gateway       | Usage telemetry                       | `LITELLM_TELEMETRY=False` – set in the reference deployment                     |
| LLM gateway       | Model price list, fetched at start-up | `LITELLM_LOCAL_MODEL_COST_MAP=True` – set in the reference deployment           |
| LLM gateway       | List of Anthropic beta headers        | `LITELLM_LOCAL_ANTHROPIC_BETA_HEADERS=True`                                     |
| vLLM, if used     | Usage statistics                      | `VLLM_NO_USAGE_STATS=1`                                                         |
| Container runtime | Image pulls                           | Mirror the images; set `LITELLM_IMAGE`, `CONTEXT_FORGE_IMAGE`, `POSTGRES_IMAGE` |

There is no licence activation and no telemetry from Visdom components.

## Fully air-gapped

Models are served inside the network (see [Models and routing](/visdom-ai-gateway/user-guide/models-and-routing.md#models-inside-the-network)) and tool servers are internal. Keys, teams, budgets, allow-lists, spend and the MCP registry all work unchanged.

## Through a corporate proxy

Cloud models can still be reached through the organisation's forward proxy. Set `HTTPS_PROXY` and `NO_PROXY` on the gateway services and, for a private certificate authority, `SSL_CERT_FILE`. Keep the allow-list of provider hosts at the proxy.

## Updates

Today an update is a new set of mirrored images, pinned by digest. Signed offline update bundles are on the [roadmap](/visdom-ai-gateway/roadmap.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.visdom.virtuslab.com/visdom-ai-gateway/user-guide/offline-and-air-gapped.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
