Hmmm. Ok then. I seem to have broken my #opnsense configuration and cannot access anything. Like anything at all. WTF.
Even plugging my laptop directly into the #proxmox server nic, and setting my laptop nic settings to what should be the network, I can't get to the proxmox or opnsense servers.
Am I going to have to completely rebuild and configure the whole setup again? I cannot believe I did this. What a bonehead move. I don't even have a spare router handy I could use temporarily. Ugh.
