# Configuring the connector to work in a closed network

## Why isn\`t standard solution suitable

1. License availability is checked by request to the licensing server lk.bx24asterisk.ru. It is impossible to check the license without Internet access.
2. For the application to work in Bitrix24 it is necessary to receive tokens through the authorization server oauth.bitrix.info (once during initial setup and then automatically once an hour). Without Internet access, the module will not be able to access the portal, even if the portal is in the same closed network.
3. Updates of the module with new functionality are released on a regular basis. In the standard solution, updates are downloaded from our website bx24asterisk.ru and installed by the update.sh script in the module delivery, but without access to the Internet updates cannot be downloaded.

Itgrix\_bx integration module is able to work with **Bitrix24 boxed portal** in the **network without Internet access**.

This mode of operation requires:

* perform offline authorization using the "Itgrix: Offline Authorization" module;
* get a license key (offline license);
* [when releasing new versions](/changelog-bx.md), [perform offline updates](/faq/offline-update.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.itgrix.com/setup/itgrix-setup-bitrix24-asterisk/configuring-the-connector-to-work-in-a-closed-network.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.
