No traffic on WAN, gateway status down, errors "arpresolve: can't allocate llinfo for <WAN IP> on igb1
-
I have a WAN configured on IGB1 of an SG5100. It's connected to an ATT Netgear MR1100 router ... LTE-connected
Yesterday it was all working, I had VPN connectivity to another site, traffic flowing, etc.
Today, the WAN interface shows it gets the same public IP I was getting yesterday, with the same gateway. But Status -> gateways is down and the gateway won't ping. I'm not using a custom monitor, it's just using the assigned gateway. I even tried disabling gateway monitoring, but no change.
I can connect my laptop directly to the MR1100, it gets the public and can surf.
In Status -> System Logs -> General there are many entries showing "arpresolve: can't allocate llinfio for <insert WAN IP here> on igb1"
I found this post: https://forum.netgate.com/topic/136089/solved-and-revised-2-4-4-release-arpresolve-can-t-allocate-llinfo-for-gateway-on-interface0-dhcp-mtu-576
and tried setting the Option modifers to "supersede interface-mtu 0", disabled and re-enabled the interface, but I just continue to get that error and no traffic.

How? PPP, DHCP, etc?
Some hints on this in the logs?
