Hi everone, basically what the title says. I am just starting my homelab and I am somewhat conflicted on whether I should run Opensense in Proxmox or should I buy a n100 device dedicated for it. What are some of the pros and cons of doind either or. So far in my research I have only come across articles/forum posts explaining how to run Opensense in Proxmox.

I currently have the exact same question in my head. I think I'll go the following route: Install opensense in a VM on my Proxmox host (it has 2 NICs) and just put my lab stuff behind it in it's own lan. Everything connects to the router via firewall.

Benefits:

  • The rest of the lan (e.g. partner's devices) do not rely on my firewall working
  • I don't need to buy anything, I can switch to bare metal later if I need to and have figured out what exactly I need
