# Prerequisites

Last updated Aug 25, 2026|Copy as Markdown|[View as Markdown](https://4f1c5cd2.previews.developers.cloudflare.com/learning-paths/replace-vpn/get-started/prerequisites/index.md)|[Agent setup](https://4f1c5cd2.previews.developers.cloudflare.com/agent-setup/)

To make the most of this learning path, make sure that you have the following:

* A device that can run [Cloudflare One Client](https://4f1c5cd2.previews.developers.cloudflare.com/cloudflare-one/team-and-resources/devices/cloudflare-one-client/download/), Cloudflare's endpoint agent.
* A private network with applications or services that are available locally or via a VPN.
* A [host server](https://4f1c5cd2.previews.developers.cloudflare.com/cloudflare-one/networks/connectors/cloudflare-tunnel/configure-tunnels/tunnel-availability/system-requirements/#recommendations) on the private network that can run the lightweight Cloudflare Tunnel daemon process.
* (Optional) A [Linux host server](https://4f1c5cd2.previews.developers.cloudflare.com/cloudflare-one/team-and-resources/devices/cloudflare-one-client/download/#linux) on the private network that can run Cloudflare Mesh. This is only needed for server-initiated traffic flows such as Microsoft SCCM, Active Directory (AD) updates, and DevOps workflows that require server-initiated connections.
