In our last article, I showed you how my lab serves as a powerful, centralized environment for all my coding projects. But what's the point of a central server if you can't access it from anywhere? As a student who splits time between home and a hostel, I needed a way to securely connect my laptop to my homelab no matter where I am.
This article is all about how I solved that problem. We'll look at why a simple solution isn't always the best and then dive into the tool that made my life so much easier.
The Problem with Port Forwarding
When I first started, my initial thought was simple: just open a port on my home router and point it to my homelab's IP address. This is called port forwarding. In theory, it works, allowing external traffic to bypass the router and reach a specific device on your internal network.
However, I quickly learned this is a terrible idea. Opening a port on your router is like leaving the front door to your house wide open. It exposes your homelab and potentially your entire home network to the internet. This makes it a prime target for hackers and malicious bots that are constantly scanning for vulnerabilities.
The Solution: A Secure Tunnel
The answer to this problem is a Virtual Private Network (VPN). Think of a VPN as a private, encrypted tunnel through the public internet. It allows your devices to communicate with your homelab as if they were on the same local network, even when they're miles apart. This keeps your connection private and secure, as no one can see what's happening inside the tunnel.
Traditionally, setting up a VPN server can be complicated. You'd need to configure a server on your homelab with something like OpenVPN or WireGuard, manage certificates and keys for each device, and deal with complex firewall rules. As a beginner, this felt like a huge obstacle.
The Game-Changer: Tailscale
Then I found Tailscale. It completely changed the game for me. Tailscale is a mesh VPN service that builds on the WireGuard protocol but makes the setup incredibly simple. It creates a private network that securely connects all your devices—laptops, phones, servers—regardless of their location.
Here’s how it works:
Install Tailscale on each device. I installed it on my homelab server, my laptop, and my phone.
Log in with the same account. As soon as each device logs in, they all become part of the same private Tailscale network.
Done! That’s it. There's no need to configure complex firewall rules or mess with router settings.

With Tailscale, I can access my homelab server from my hostel as if it were sitting right next to me. I can securely SSH into my server, connect to my VS Code Server instance, and even access my self-hosted services using their private Tailscale IP addresses. It’s all seamless, secure, and incredibly easy.
For a beginner like me, Tailscale was a godsend. It removed the biggest barrier to remote access and allowed me to get straight to the fun part of using my homelab. And it helps me reduce complexity to access my node in my parent’s home.
