Virtualizing OPNsense on Proxmox as Your Primary Router
Are you curious how to set up OPNsense on Proxmox as your primary router? In this video, I show one way you could go about doing it using the Protectli VP6650, but you may adapt this guide to the hardware you wish to use.
This guide assumes you have an existing network and that you are planning to migrate to a virtualized instance of OPNsense. The guide also does not do a full network configuration in OPNsense in an effort to keep the video shorter. Once you have OPNsense up and running, you can use other guides I have created to configure OPNsense for your network.
The focus of this video is getting Proxmox configured properly, creating the OPNsense virtual machine, and showing how to physically connect everything to your network. You must be careful to not conflict with your existing network once you have the OPNsense VM set up (conflicting IP addresses, multiple DHCP services running on the same network, etc).
I recommend disconnecting the Proxmox server from your network or connecting it to a dedicated VLAN with different IPs to avoid issues with your existing network if you wish to do more testing before swapping out hardware.
