### Overview <a href="#overview" id="overview"></a>

It may be necessary to create a connection into a target system which blocks ingress connections or is behind a firewall, particularly if you cannot install Keeper Connection Manager on a device within the target network.&#x20;

For this use case, Keeper Connection Manager supports the use of reverse SSH tunnels. This guide provides a method of setting up a reverse SSH tunnel to access a system that is otherwise inaccessible due to inbound network restrictions.&#x20;

This guide covers reverse SSH tunnels using the Auto Docker Install method and a target endpoint. Once the tunnel and configuration is complete, Keeper Connection Manager can establish a connection to the remote endpoint through the tunnel.  You can use any supported connection within the tunnel, one established.

### Using KeeperPAM instead of Reverse SSH Tunnels

Keeper's cloud-based product called KeeperPAM provides zero-trust encrypted connections through the Keeper vault. This eliminates the need for reverse SSH tunnels.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.keeper.io/keeper-connection-manager/supported-protocols/persistent-reverse-ssh-tunnel.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
