General Discussion / Can't get WAN IP on new install
« on: November 25, 2023, 08:43:04 pm »
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. I asked if they were receiving my DHCP requests at all and was told that their supervisor told them the "*DPHC* is there if you see the signal".. and could not give me any information about any specific configs they'd require, etc. They said they did something that could help reset things but would not tell me what it is that they did. It did not help. I still don't even know if I should be using IPv4 or IPv6 because he didn't know that, either.
What I've tried:
I ran a packet capture on the WAN port and the only thing I see is a bunch of DHCP requests being sent out. My modem 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.
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 really sure what to do next/where to look to troubleshoot this further.

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
