I see a lot of people saying using firewalls in vms is dangerous and could eventually lead to a cascading error. I want the firewall for home use. Should i use opnsense barebone or proxmox in my situation? I already have a machine running proxmox and i dont want to buy another one.
It's a bit more complicated to do but has pros and cons, as anything.
I moved in my home/home-lab from baremetal to VM on Proxmox and just deal with the different ways of doing things. Again, enjoying the pros and managing the cons.
You can run the firewall as VM in any kind of virtualization. What they mean is, that when your Hypervisor fails, most of your network infrastructure will be unavailable. Essentials like DHCP, Router Advertisements, DNS etc... stop to work while you have to troubleshoot the Hypervisor itself.

so basically no security nature issues just the whole system fails right? so nothing to be worried about. i mean, there will be some security flaws but not that important and manageable right?
The issue is more about availability than security. I run and ran lots of OPNsense VMs productively. But at home I have a Deciso box because I don't wanne troubleshoot for hours in my free time anymore.
well i guess i have to go with using opnsense in proxmox ;D thanks so much for the clarification
