What is Tailscale and why should WFH users in India care?
Short answer: Tailscale is a mesh VPN (Virtual Private Network) built on WireGuard — the fastest modern encryption protocol. Unlike a traditional VPN that routes all traffic through a distant server, Tailscale creates direct encrypted tunnels between your own devices. Your home laptop, office desktop, NAS drive, and phone all join a private network called a tailnet (Tailscale network) — and you can access any of them from anywhere in India as if you were on the same local Wi-Fi. Setup takes under 5 minutes and the personal plan is free.
How to set up Tailscale on Windows and Mac
Step 1: Create a Tailscale account and install the app
Visit tailscale.com and sign in with Google, GitHub, or Microsoft account — no new password to create. Download the Windows or macOS installer for your laptop. Run the installer (requires administrator rights on Windows). After installation, the Tailscale icon appears in the Windows system tray or Mac menu bar. Click it and sign in with the same account. Your laptop is now part of your tailnet and has received a private Tailscale IP address in the 100.x.x.x range. This address is consistent across all networks — it works whether you are on home Wi-Fi, a café hotspot, or a phone hotspot. Install Tailscale on your phone too from the App Store or Play Store, log in with the same account, and both devices are now securely connected.
Step 2: Connect to another device remotely
On Windows, open a File Explorer window, type \\100.x.x.x\ (the Tailscale IP of your home or office device) in the address bar. If Windows file sharing is enabled on the remote device, you will see its shared folders. For SSH access to a Linux server or Raspberry Pi: open a terminal and type ssh username@100.x.x.x. For Remote Desktop to a Windows machine: open Remote Desktop Connection and enter the Tailscale IP. No port forwarding, no dynamic DNS, no firewall rules required — Tailscale handles all of this automatically. This is the main advantage over traditional VPN setups in India, where ISP router configurations and CGNAT (Carrier-Grade NAT — when your router shares a public IP with other customers, common on Jio and BSNL) make port forwarding painful.
Step 3: Enable Subnet Routing (optional — for office network access)
If you want to access your entire office network (printers, internal servers, legacy applications) through Tailscale, not just a single device, enable Subnet Routing on the office machine. On the office computer, run: tailscale up --advertise-routes=192.168.1.0/24 (replace with your office network's IP range). In the Tailscale admin console (login.tailscale.com/admin), approve the route. Your home laptop will then route traffic to office IP addresses through the Tailscale tunnel — effectively the same as a site-to-site VPN without any hardware routers or firewall configuration. This is popular among Indian startups and small offices with 5–20 employees who need secure remote access without a dedicated VPN appliance.
Step 4: The India context — CGNAT and Exit Nodes
Jio GigaFiber, BSNL, and some Airtel plans use CGNAT — your home router does not have a public IP, making traditional remote access solutions (Hamachi, WireGuard self-hosted, OpenVPN) fail or require complex relay setup. Tailscale handles CGNAT automatically using its DERP (Designated Encrypted Relay for Packets) servers. When direct connection is blocked, traffic relays through Tailscale's nearest server (Singapore for most India locations). Speed is slightly reduced but the connection works. Tailscale also supports Exit Nodes — one device in your tailnet can serve as a full VPN exit for others, routing all internet traffic through it. This is useful if you need to appear to be on your office network for compliance reasons. Read our slow VPN fix guide for tuning WireGuard performance if Tailscale speeds are slower than expected.
When to call a laptop repair service (and what it costs in India)
When DIY ends
Tailscale setup is entirely software-based — no hardware repair needed. The only scenario requiring a technician: if Tailscale keeps disconnecting because the Wi-Fi adapter on the laptop is failing, or if the laptop cannot install Tailscale due to Windows corruption (use the Windows DISM and SFC tools to repair Windows first, or see our Windows reinstall service).
Typical repair cost in India
Tailscale itself is free. If the underlying Wi-Fi hardware fails: Wi-Fi card replacement ₹800–₹2,500. Windows reinstall if OS corruption prevents software installation: ₹500–₹1,500. Doorstep diagnosis: ₹149.
A note from the LRW Engineer Team
We have started recommending Tailscale to many WFH customers who come to us frustrated with traditional VPN speed and complexity. The zero-config approach means there is nothing to misconfigure, and the WireGuard protocol underneath is genuinely fast — most users notice no speed difference from their regular network. The free tier is generous enough that an entire household's devices can be on the same tailnet for a secure personal mesh without any ongoing cost.
