I'm having trouble getting DHCP to work on WAN.
I have an AT&T fiber connection typically connected via a BGW210-700. Cert extraction, wpa_supplicant, etc all works just fine. DHCP does not.
Here is output from system log view on the portal:
I ran tcpdump on the WAN interface and see offers coming back (uniquely identifiable information is replaced with 'x's):
I'm at my wits end with this. I can even get DHCP6 to work, but not DHCP4 so I doubt it's the link.
