DHCP Leases / Roaming Clients

Unanswered Question

We have several remote locations that we just installed Aironets at. All the locations are setup to forward DHCP packets to our centralized DHCP server(s) via ip-helper. Here is the situation. I took a wireless client to location A (10.10.0.0/16), obviously the client got an IP and worked. However, I goto location B later that day (10.40.0.0/16) and the client immediately gets the old lease (from the 10.10.0.0/16 block).


My question is, is there any way around this save for dropping our lease time down significantly? Thanks for any thoughts or ideas you might have.

Release DHCP Lease on Shutdown option can be used to control whether DHCP-enabled computers running Windows 2000, Windows XP, or Windows Server 2003 sends a DHCPRelease message to the DHCP server when a shutdown occurs. It is actually implemented and interpreted as a bit-masked value by the DHCP Client service. By default, these clients do not send DHCPRelease messages on proper shutdown.
