## Get Started

- [Overview](https://developers.telnyx.com/docs/network/tunnel.md): A Tunnel connects a Network to the user's site without any modification to its router or firewall.
- [Quick Start](https://developers.telnyx.com/docs/network/tunnel/quick-start.md): Reach a subnet behind a Tunnel from an Edge Compute function, without any modification to the user's router or firewall.
- [Beta Limitations](https://developers.telnyx.com/docs/network/tunnel/beta-limitations.md): What the Tunnel beta does not do yet.

## Concepts

- [What It Is Not](https://developers.telnyx.com/docs/network/tunnel/concepts/what-it-is-not.md): A tunnel is not an interface, a link, or a route, seen from either side. Each point below shows it on the Quick Start setup.
- [What It Is](https://developers.telnyx.com/docs/network/tunnel/concepts/what-it-is.md): A tunnel is a process within the user's network on one side, and the next hop of a route or the target of a service or hostname on the other. Each point below shows it on the Quick Start setup.
- [Connections](https://developers.telnyx.com/docs/network/tunnel/concepts/connections.md): How a request from a Network reaches a host behind the tunnel, step by step.
- [Lifecycle](https://developers.telnyx.com/docs/network/tunnel/concepts/lifecycle.md): The statuses of a tunnel and its routes, from the first connected process to deletion.

## Features

- [Routes](https://developers.telnyx.com/docs/network/tunnel/features/routes.md): How a route on a Network sends a subnet to a tunnel.
- [Private Services](https://developers.telnyx.com/docs/network/tunnel/features/private-services.md): Register one service behind a tunnel on a Network, under a private hostname, without routing the subnet around it.
- [Public Hostnames](https://developers.telnyx.com/docs/network/tunnel/features/public-hostnames.md): Publish a service behind a tunnel at a hostname the user owns, through a CNAME to Telnyx.

## Operations

- [Run as a Service](https://developers.telnyx.com/docs/network/tunnel/operations/run-as-a-service.md): Install the tunnel process as a system service that starts at boot and restarts on failure.
- [Test a Destination](https://developers.telnyx.com/docs/network/tunnel/operations/test-a-destination.md): Check that the tunnel host reaches a destination, without Telnyx in the path.

## API Reference (Tunnel)

### Tunnels

- [List all Tunnels](https://developers.telnyx.com/api-reference/tunnels/list-all-tunnels.md): Lists the tunnels on the account with their status and connected tunnel processes. Responses never include `tunnel_token`.
- [Create a Tunnel](https://developers.telnyx.com/api-reference/tunnels/create-a-tunnel.md): Creates a tunnel and returns its `tunnel_token`. The token is the only credential the tunnel process needs, and this response and `POST /tunnels/{id}/actions/r…
- [Retrieve a Tunnel](https://developers.telnyx.com/api-reference/tunnels/retrieve-a-tunnel.md): Retrieves a tunnel with its status and the tunnel processes connected to it. The response never includes `tunnel_token`.
- [Delete a Tunnel](https://developers.telnyx.com/api-reference/tunnels/delete-a-tunnel.md): Deletes a tunnel. A tunnel that a route names as its next hop cannot be deleted; delete those routes first. Connected tunnel processes are disconnected and can…
- [Rotate a Tunnel Token](https://developers.telnyx.com/api-reference/tunnels/rotate-a-tunnel-token.md): Issues a new `tunnel_token` and invalidates the previous one. Tunnel processes already connected stay connected until they reconnect, and are then refused unti…
