dhcp failing to report online
-
Not sure if anyone has experienced this or knows what may be wrong as I have no idea where to start.
Basically I have Pfsense installed on a server running PPoe with a router in bridge mode. Now I have two more servers that run containers and VM's. I've set up DHCP with Pfsense and it is giving out ip's from its pool. But the problem is that when I check DHCP lease I can see that some of the containers are offline, yet when I ping them they respond. I can direct access them through the ip address but Pfsense insists that the container is offline.
I've checked cables and run packet tests and everything seems to be working fine. -
@Halfhidden said in dhcp failing to report online:
are offline
The "idle/offline" or "active" indication reflects the presence of the MAC in the pfSense arp cache.
The arp cache doesn't have a duration of the DHCP lease, it's OS depended and far smaller.
See Diagnostics > ARP Table
Ping, from pfSense, an IP that has a lease.
Check Diagnostics > ARP Table again : now the IP + MAC of that device is present in the ARP table..... and back again on the DHCP lese page : the lease is now marked 'green and active'.

@Gertjan
That's great information. I'll follow your guidance.
That also make perfect sense as I have cloned a container that has been allocated the same IP address as the predecessor. Obviously a new Mac would have been created by the hypervisor.
Thanks again for fantastic information
