DHCP shows device offline but I can ping it
-
This seems like it should be obvious but what does Offline mean in the Status/DHCP Leases page?
We're trying to troubleshoot a tenant connection that is using a static DHCP mapping based on the MAC address. DHCP logs show the IP was assigned. I can ping it. But twice today that I've noticed the DHCP Leases status page shows it offline, but other times it is shown as online. The ARP table doesn't list the IP or MAC address but that is expected as my traffic to that router would go through a switch and not get to pfSense.
Does that page only see it "online" if there is traffic from it to the pfSense? I just pinged it from the pfSense and it shows online now and is in the ARP table.

You mentioned the answer in your question
The "offline" just means that there is no trace of the IP in the Diagnostics > ARP Table.Ping it, " WOL" it, make it awake and aware, and you'll see the ARP table contains the IP => the device will show as "online".

OK thanks just needed confirmation. :)
