Personal VPN-as-a-Service with OpenZiti and Tailscale

 

English Alt Text: A four-panel comic titled “Personal VPN-as-a-Service with OpenZiti and Tailscale.” Panel 1: A user says, “I don’t want to expose my ports,” and another replies, “Use Ziti to go dark!” Panel 2: A man holds a phone and says, “Tailscale connects all my devices—no config needed!” Panel 3: A network diagram shows Ziti tunneling an app and Tailscale routing the user securely. Panel 4: A woman smiles at her screen and says, “Private, secure, and no servers to manage!”

Personal VPN-as-a-Service with OpenZiti and Tailscale

Traditional VPNs often require complex setups, expose infrastructure to the public internet, and struggle with modern zero trust demands.

OpenZiti and Tailscale offer a modern, lightweight way to build personal VPN-as-a-Service solutions that are secure, peer-to-peer, and easy to scale.

In this post, we’ll walk through how to use both tools to spin up private overlay networks for personal or small business use cases—without managing your own VPN server.

🌐 Why a Modern Take on VPNs?

Legacy VPNs rely on public endpoints and often trust devices implicitly once connected.

Newer models like Zero Trust Network Access (ZTNA) enforce access control at every layer and decouple identity from IP.

Tools like Tailscale and OpenZiti let you build private overlay networks without exposing infrastructure to the open internet or maintaining centralized servers.

πŸ›‘️ OpenZiti for Zero Trust Networking

OpenZiti is an open-source platform for building dark networks—meaning no part of your system is exposed unless explicitly allowed.

Features include:

- Identity-based access, not IP-based

- No open ports required

- SDKs for embedding Ziti into your apps or services

- Central controller for policy enforcement

πŸ”’ Tailscale for Easy Peer-to-Peer Access

Tailscale uses WireGuard under the hood to create encrypted mesh networks between devices.

- Auto-discovers peers across NATs and firewalls

- Uses your identity provider (e.g., Google, GitHub) for authentication

- NAT traversal and device tagging built-in

- Perfect for connecting laptops, mobile devices, servers securely

⚙️ How to Combine OpenZiti and Tailscale

Use OpenZiti for services that should not be directly exposed (e.g., internal apps, APIs).

Use Tailscale to connect devices and enforce user-based access to those Ziti-hosted apps.

Example Flow:

1. Deploy Ziti Edge Router and Controller (or use hosted NetFoundry)

2. Publish your service through a Ziti tunnel

3. Connect your devices via Tailscale and route requests through localhost to your Ziti endpoint

4. Authenticate with identity-aware Ziti policies and access controls

πŸ’Ό Real-World Use Cases

- Access your homelab securely from anywhere without port forwarding

- Connect to private SaaS dashboards or customer admin panels

- Secure IoT or Raspberry Pi devices without assigning public IPs

- Enforce user-specific access to dev/test/prod environments

- Build a lightweight, serverless VPN solution for remote teams
