Remove entries from Client List on Peplink 380?

Is it possible to remove entries from the Client List table (Status -> Client List) on the Peplink Balance 380 (I am running firmware 5.4.9)? I have a lot of entries that are always offline and have no Name associated so would like to get rid of them. I looked through the manual but cannot find a way to remove them.

Hello,

There is no way at this time to release IP addresses manually. The offline clients will have the IP saved to the MAC-Address associated to the device for the period of time set under Network>LAN>DHCP Lease Time. You could try to lower the Lease Time amount (default is 1 day).

Thanks Jarid, I will try that.
