I'm switching over from an Omada router to OPNsense. I have it installed as a virtual machine with Proxmox. LAN seems to be working fine, but I can't get a WAN IP address.
I don't believe that my ISP requires that I provide them with the new mac address because I've switched routers in the past without issue, but I called just in case. They were not helpful and wouldn't provide any information.
What I've tried:
I ran a packet capture through OPNsense on the WAN port and the only thing I see is a bunch of DHCP requests being sent out. My modem (CM1200) has no errors. It logs a "DHCP non-critical field invalid in response" error every time it reboots, but it does that no matter what router I use. Bridge mode is not applicable for my modem.
There was one point for about ten minutes that I got it to come on a few days ago and everything was fine, but then the IP address was lost and I haven't been able to get it back. I'm not sure how to figure out if this is a problem with my network or a problem with my Proxmox configuration, or what troubleshooting steps to do at this point.

What I've tried:
- Spoofing the mac address with the one from my old router
- Turning on/off private IP addresses
- Turning on/off bogon IP addresses
- Overriding MTU
- Resetting modem and waiting 30 minutes
- Turning on/off Ipv6 DHCP
- Installing PFsense instead (same issue)
