How to Access Your Home Network Remotely Using Tailscale

Introduction to Remote Access

• The video discusses the utility of accessing home networks remotely, particularly in scenarios involving public Wi-Fi or sharing streaming services with family members.

• It highlights the need for secure access to devices like NAS or media servers (Plex, Jellyfin) without compromising security by opening router ports.

Overview of Tailscale VPN

• Tailscale is introduced as a user-friendly VPN solution that requires no complex configurations or port openings.

• The speaker emphasizes installing Tailscale on various devices within the home network for seamless communication and safety.

Device Compatibility and Setup

• Tailscale can be installed on multiple operating systems and devices, including Windows computers and Apple TVs, although these may not be ideal due to power management issues.

• A Raspberry Pi is recommended for installation due to its low power consumption and ease of setup; models 3, 4, or 5 are suitable.

Requirements for Installation

• To set up Tailscale, users will need a Raspberry Pi (preferably model 5), a micro USB card, and potentially a USB reader if their computer lacks one.

• The speaker notes that Tailscale is free for up to three users and 100 devices, making it accessible for personal use.

Step-by-Step Installation Process

• The video promises a straightforward step-by-step guide on installing Raspbian OS on the Raspberry Pi using an application called Raspberry Pi Imager.

How to Set Up SSH and VNC on Raspberry Pi

Activating SSH and Preparing the MicroSD Card

• The process begins by activating SSH with password authentication on the second tab of the configuration. After enabling it, save changes and confirm overwriting the microSD card.

• Once saved, allow a few minutes for recording and verification on the microSD card before removing it from the reader.

Connecting Raspberry Pi to Network

• Insert the microSD card into the Raspberry Pi, connect a network cable (preferably wired), and power it on. This initial boot may take several minutes.

• To find the IP address of your Raspberry Pi, use a terminal command ping followed by its hostname (e.g., vpnTailscale.local). Alternatively, check your router's HTTP configuration.

Accessing Raspberry Pi via SSH

• Use SSH to access your device by entering ssh followed by your username and IP address. Input the previously set password to log in.

• Enable VNC by typing sudo raspi-config, navigating to interface options, selecting VNC, and confirming its activation.

Installing VNC Client

• Download a VNC client like RealVNC for Windows; installation is straightforward.

• In the VNC client, input your Raspberry Pi's IP address to connect. Enter your configured username and password when prompted.

Configuring Static IP Address

• It’s recommended to configure a static IP for easier access. Edit connections under Wired Connection 1 in IPv4 settings; switch from DHCP to manual configuration.

• Choose an appropriate static IP outside of your DHCP range (e.g., 192.168.0.x), set subnet mask (255.255.255.0), and gateway as your router's IP before saving changes.

Setting Up TailScale VPN

• Create a free user account on TailScale using services like Google for easy login.

• Install TailScale client on Raspberry Pi by copying provided commands into terminal; this will initiate installation after hitting Enter.

Authenticating Device with TailScale

• Post-installation, run sudo tailscale app which generates an authentication URL for logging into TailScale via browser.

Configuring Subnet Router in TailScale

• Configure Subnet Router within TailScale allowing local network exposure to connected clients—enabling access to devices like NAS or Plex remotely.

Finalizing Routing Configuration

• Execute specific commands shown in terminal for routing setup within local network through TailScale.

How to Configure TailScale on Raspberry Pi

Setting Up IP Range and Client Configuration

• The user must input their specific IP range, commonly in the format 192.168.x.x/24, which can be found in the router's configuration.

• It's crucial to configure or accept settings in the TailScale administration panel; otherwise, they won't function properly.

• Users should enable subnet routing by editing root settings in the TailScale admin panel to expose local networks to connected clients.

Configuring Raspberry Pi as an Exit Node

• To allow traffic through the Raspberry Pi as an internet output node, execute the command sudo tailscale set-advertise-exit-node once.

• After executing the command, return to the TailScale console and enable the node as an exit node via route configuration.

Finalizing VPN Configuration

• It is recommended to disable key expiry for convenience, preventing frequent re-authentication issues from occurring within the TailScale admin panel.

Connecting Additional Devices (Android Example)

• Install the TailScale app from Play Store on Android devices and grant permission for VPN management before logging into your account.

• Once connected, users can access their local network even while using mobile data (5G), demonstrating seamless integration with existing networks.

Managing Traffic and Security Features

• Users can switch between different exit nodes without advanced settings, allowing them to control their internet traffic location easily.

• The TailScale administration console provides comprehensive device management options including activity logs and user invitations for up to two additional accounts on a free plan.

Key Benefits of Using TailScale

• Accessing home resources securely is vital for protecting personal files and documents stored at home.
