      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.

        @dlogan said in 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.

        How? PPP, DHCP, etc?

        Some hints on this in the logs?
