Thank you for responding so quick!
Yes, when I would reboot the box that held opnsense, I would lose my WAN IP when it came back up. I had to power cycle the modem to get a new WAN address. Yes, I meant a 2 PC Proxmox cluster. As you suggested, I separated my cluster so that I have two independent Proxmox machines again. I basically reinstalled everything to make sure they were truly separate.
After reading through your response a couple of times, I believe that Proxmox is sending out the MAC address of the network port that is assigned as my WAN port even though it is not configured with an IP. When OPNsense starts up, a new MAC address is broadcast so I am not given an IP until I power cycle the modem. I did try to use the MAC address (I think it was the MAC address I grabbed) of the network adapter assigned in Proxmox. When I added it to the WAN port config to spoof Proxmox, I was given an IP from my ISP, but I could not reach the internet. I removed the spoofed MAC and I got an IP and could browse the web.
I need to do some more testing I suppose to figure out how to get this working. :)
QuoteDoes that happen only when (one of) your Proxmox host restarts or also if you only restart the OpnSense VM?
And what do you mean with a "2 PC cluster"? Is that a Proxmox cluster?
