Hi all! I’m trying to jump into the whole homelab thing with both feet. I recently got into Proxmox and I want to set up OpnSense with high availability as my primary router. There are plenty of tutorials and videos online for it, but they all seem to focus on the software aspect of it. No one that I’ve been able to find really talks about the hardware setup. I’ve found one video where a YouTuber summarizes his hardware setup to achieve it, but doesn’t go into any real detail. (video here)
I’m no stranger to IT, but my knowledge is a bit dated, e.g. I understand the concept of VLANs, but implementing them still kind of escapes me. Familiarizing myself with newer (to me) concepts is part of why I’m trying to learn. To give you an idea of the gaps in my knowledge – I have Network+ and Security+ certifications from 2010, and everything since then has been learn as needed for work.
Right now, I have AT&T 1Gbps fiber. The modem is set to passthrough mode, and I’m using a TP-link Archer A9 router that I’m trying to replace with OpnSense. I gather for failover to occur, there would need to be a physical connection from the modem to each of the PCs in the cluster. The diagram is how I would understand it, but I’m a little stumped on how the 5-port switch that feeds each node would need to be set up or if this config would even work.
Does anyone have any advice or could you point me in the direction of a good hardware guide/tutorial in order to get this going? Thanks!
