Hi.

We are using several RUT240 units running the most recent stable firmware.

We have between 8 and 20 devices connected to each unit, and the devices are all assigned their IP address from the RUT240 based on their MAC address.

However when the menu "Staus/Network/LAN" is entered the RUT240 says "Collecting data" and then shows a list of DHCP leases.

The issue is that it only shows about half of the devices. It shows for example 8 devices, eventhough I know that 18 devices are connected, and they all have been assigned IP's by DHCP since I can ping them. The DHCP lease time is 12 hours.

Why aren't all the DHCP leases shown in the list?

The devices are connected to the RUT240 LAN port through a 16 port normal switch. Not managed or anything special.

Thanks in advance

Hi,

I believe that's the WebUI limit. To show full list of DHCP leases - execute this in CLI: cat /tmp/dhcp.leases

Hi.

I don't think that it is a limit with the WEBUI. Because sometimes it shows almost all the clients, and sometimes only half of them or less.

In the DHCP leases list under "LAN name" it shows "Lan" for some devices and empty for other devices. All the devices are connected to the same switch though, and even devices of the same type, are not shown the same way.

I think the DHCP leases list is not quite functioning as it should.

Sometimes DHCP leases might be not shown because devices have static IP's set and that would mean that they didn't get a DHCP leased by the router. Could you confirm that every device is set to gain automatic IP by DHCP? Also, does the command I've sent you show all the devices when you're missing them in WebUI?
