When running privacy-sensitive applications through a VPN, one of your biggest concerns should be connection drops.

In this guide, we’ll build a robust, self-hosted VPN kill switch using Docker containers and iptables firewall rules. You’ll learn how to create an isolated network namespace where applications can only communicate through the VPN tunnel—if the VPN drops, all traffic stops completely. We’ll use qBittorrent as our example application, but the same approach works for any Docker container. ...

If you’ve ever wanted to track your internet speeds over time without relying on third-party services that log your data, self-hosting your own speed test tool is the answer. Two of the most popular options in the homelab community are LibreSpeed and Speedtest Tracker — and they serve surprisingly different purposes despite sharing a similar name space. 💡 This article contains affiliate links.

In this guide, we’ll break down what each tool does, how to set them up with Docker, and which one makes sense for your homelab. By the end, you’ll know exactly which to deploy — or whether you need both. ...

Pi-hole is one of the most popular self-hosted tools in the homelab community — and for good reason. It blocks ads, trackers, and malicious domains at the network level, protecting every device on your network without installing anything on individual devices. Smart TVs, smartphones, game consoles — they all benefit automatically. In this guide, you’ll learn how to run Pi-hole in Docker, configure it properly, set up custom DNS records, and squeeze every last bit of blocking power out of it. ...

When you’re running a homelab, secure remote access is essential.

In this comprehensive guide, we’ll compare both solutions, provide complete setup instructions, and help you decide which one fits your homelab. ...
