Hi. I have a strange problem.
I have a network printer. In this printer I set up a manual IP adress and everything works very well. But I have a IP conflict which is little strange.
When I go to: Fortiview -> Seources and try to search about that IP I see another (android device) with this IP assigned (?).
So I go to Network->Interfaces-> DHCP server -> Advanced and do two steps:
1. Add MAC reservation for my printer MAC and assign them these same IP as printer,
2. Add MAC block for that android device.
But I dont knwo ho to force "unassvcigned" that android device from that adress. I try execute dhcp lease-clear 192.168.100.5, but these don't work (I think). I aso try to End sessions in that IP in Soirces, but also don't work. I don't see then that IP in Sources, but after while I see these same android device.
In "User and device"-> Device Inventory I see for that IP adress two devices - my printer which is offline and that android device which is online.
How to fix that rhings ? How can I force to release that IP fro that android device? Is it possible to force that connection somehow?
