# RAS Secure Gateway

RAS Secure Gateway は、すべての Parallels RAS データを 1 つのポート上でトンネリングします。また、RAS Secure Client Gateway は、セキュアな接続を提供し、Parallels RAS へのユーザー接続点となります。

すべてのサイトに対して、最低 1 つの RAS Secure Gateway をインストールし、構成する必要があります。あるサイトがテナントとして RAS テナントブローカーに参加する場合、RAS Secure Gateway は不要です。詳細については、[**「RAS マルチテナントアーキテクチャ」**](https://download.parallels.com/ras/v19/docs/ja_JP/Parallels-RAS-19-Administrators-Guide/45415.htm)を参照してください。

要件によっては、複数のゲートウェイが存在する場合があります。この章では、RAS Secure Gateway を追加、構成、管理する方法について説明します。

## 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.parallels.com/landing/ras-admin-guide/v19-ja-jp/ras-secure-gateway.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.
