VLANs for Proxmox + OPNsense: My Homelab Setup
Source: YouTube · Christian Lempa · published Jul 10, 2026 · 20:18
Building a home lab often leads to organizational chaos, which is solved by using VLANs to segment traffic and a firewall to enforce security boundaries between isolated zones.
Key Takeaways:
• VLANs allow multiple logical networks to exist on a single physical switch, eliminating the need for additional hardware 0:17.
• A firewall enables the creation of distinct security zones, such as a private home lab, a testing environment, and a DMZ for public-facing servers 0:29.
• These zones protect critical infrastructure by ensuring that public-facing web servers in the DMZ are isolated from private internal systems 0:36.
Implementing this architecture provides essential network isolation, enhancing security and manageability for complex home lab setups.

If you are building a home lab, you will likely know this problem. Once you start adding more servers, deploying more applications, and experimenting with more gear, it's getting harder and harder to keep everything organized and connected. That's exactly why we're using VLANs, virtual local area networks, because they let you create multiple logical networks on one single physical switch without buying a whole rack of extra hardware. And together with a firewall, you can better segment your network into separate zones like one for your home lab, one for your testing environment, or a DMZ, a demilitarized zone where your public-f facing web servers are running all protected from each other. That's exactly what I did a few years ago in my home lab. But until now, I had one small problem. Al…
