Our notebooks (sales people) often leave HQ for more than a week. DHCP server is set up to expire leases after 8 days. What happens is apparent - NB's "steal" IP addresses from each others after some time.
For instance, today NB03 is here, but the Dude indicates NB05 as present.
The reason as I understand it: the Dude takes a device on the map, pings its IP address and doesn't care about what that device really is. If it echoes back, it is lit green. And eventually updates its MAC.
But this is wrong behavior. The MAC should be locked and bound to the device on the map no matter what IP it gets in the future. This way I would always know that what I see today in the network is really NB05 and not another "masked" computer.
Is it possible to set this in the Dude? I cannot find it in the preferences.
