Yes. Many clients will automatically ask for longer lease times than your default.

Dwane From: Atkins, Dwane P [mailto:atki...@uthscsa.edu] Sent: Tuesday, March 15, 2011 10:34 AM To: 'support@pfsense.com' Subject: [pfSense Support] DHCP server settings We recently lowered our DHCP lease time to the default of 2 hours. After a couple hours, I was checking the DHCP leases and see some that have a difference of 2 hours from the Start and End time. However, there are some that have a 24 hour difference. Is there a way to completely clear out the DHCP lease time and restart the DHCP server. These leases started almost 3 hours after I had modified the default lease time. Thanks Dwane
