I feel so stupid. I messed up big time today and am trying to install proxmox from scratch. The only problem is that the router VM (opnsense) was removed when I installed a fresh copy of proxmox so now I have no router.

How can I set up proxmox without a router, then connect to it locally to set up opnsense VM to actually get a router up and running so I can connect the machine to the internet?

Edit: resolved. It was a dumb overlook on my part. Learning networking the hard way, now watching videos to learn more. Good news is that my server's back up and running.
