Thank you, Adam. We had the DHCP default lease time set to 4 hours and the Maximum lease time was set to the default of 24 hours. So we lowered the default lease to 2 hours and left the maximum lease at 24 hours. What this tells me is that with the default lease, it will do another DHCP negotiation at the ½ life or in this case an hour. The maximum lease time says that 10.10.10.10 will only be allowed to lay claim to that lease for one day. Is this a correct assumption? Should I lower the maximum lease time as well?

Many clients will automatically ask for longer lease times than your default. -Adam From: Atkins, Dwane P [mailto:atki...@uthscsa.edu] Sent: Tuesday, March 15, 2011 10:36 To: 'support@pfsense.com' Subject: [pfSense Support] RE: DHCP server settings I am not trying to spam mail, but should we set the maximum lease time as well?

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
