In this blog post, we will look at how to access geo-restricted content using Tailscale’s Mesh VPN concepts.

What is Tailscale?

Tailscale is a modern VPN solution built on top of the WireGuard protocol that simplifies creating and managing secure network access between devices. It uses a mesh networking approach, enabling encrypted peer-to-peer connections, each device can connect directly to other devices within the network, without needing a central server to route traffic.

How does Tailscale Mesh VPN work?

1. Traditional VPN and 2. Tailscale Mesh VPN

A traditional VPN creates a secure, encrypted tunnel between your device and a centralized VPN server hub. This tunnel allows your internet traffic to travel securely through the server, masking your IP address and encrypting your data.

Traditional VPN flow

Tailscale uses a mesh VPN architecture, allowing direct, peer-to-peer connections between devices without a central VPN server. The Tailscale coordination server is used for authentication, key exchange, and device discovery. Once devices are authenticated and have discovered each other, they establish direct, peer-to-peer connections using Wireguard.

Tailscale VPN flow

Tailscale supports many devices (Windows, Mac, Linux, iOS, and Android), and the installation process is pretty straightforward.

So how does it allow accessing geo-restricted content?

1. Exit node flow 2. Tailscale admin console

One of the many features of Tailscale is Exit nodes, an exit node is a device within the Tailscale network that routes traffic to the broader internet on behalf of other devices in the network. This is useful for scenarios where you want to use a specific network’s internet connection, such as accessing region-specific content or securing internet traffic through a trusted network.
