IP Addresses not showing up

br116

Hi there, I'm new to PF. I'm puzzled as to why several of my active IPs do not show up in my lease list.
Is there a reason for this?
PF is the only DHCP server on my LAN.

@br116 they didn't get a lease, they were set static on the device for example

They are behind a nat wifi router is another example I could think of.

If pfsense handed out a lease, it would be listed in the lease table. Unless you had cleared the leases for some reason?

Don't stay that way !!

Check what the DHCP server is doing.

Instead of looking at the GUI DHCP log page, let's go down to the source :

Disconnect your device from the LAN.
On pfSense, open a console or SSH, option 8, and execute :

tail -f /var/log/dhcpd.log

Now, connect your device again.

Look at the console output.
You can recognize traffic coming from your device as they will contain the MAC addresses of your device.

What did you see ?

@johnpoz Interesting...they are Static on the device. Still would expect to see them. thk u.

@gertjan There is traffic, but still not showing up on Leases. I'm learning about PF...thk u

Why would they get a dhcp lease if they are set static on the device?

Do you mean you don't see them in the arp table? This you would see them in when they talk to pfsense for anything, you know like to get to the internet ;)

The only reason they would be in the dhcp lease table - if if they actually got their IP via dhcp from pfsense.

You're probably missing important info.
If you set up a device with static IP settings, like : a screen shot of one of my APs :

then the DHCP client process on that device, my AP, and your device, isn't used.
So, my AP will never emit a DHCP request, and the pfSense DHCP server will never receive a request for a lease from this device.
Because : DHCP isn't used by this device.
So : no lease.
Because you chose not to use DHCP for your device.
