NIC or Modem, more information

[Stephen Hope]

If the obsolete DHCP lease is a problem, maybe you need to set up
a lease such that it will time out before a user moves from
office to home / remote location (maybe 1 hour / 30 minutes?)

That way the lease has always vanished by the time a user sets up
remotely.
