OPNsense virtualization (programming.dev)

I’m working on setting up my first homelab. I have an older dell optiplex with a duel PCIe NIC in it. I was wondering if I could setup OPNsense as a docker container or virtual machine so that I could also use the extra resources of the box for other things besides just being a router. Is this a good idea?

Hey, as others have said, you can definitely set up OPNSense in a VM and it works great. I wanted to take a second and answer the first part of your question: it cannot run in Docker. Containers in Docker share their kernel with the Linux host machine. Since OPNSense isn’t a Linux distribution (it’s based on FreeBSD), it can’t make use of the shared Linux kernel.
