      I've got some Cisco 7940 and 7960 phones, and they picked up DHCP leases from a dhcpd server I was running on a different network from my pfsense network.  When I moved them over, they requested the old IP addresses, and the DHCP server (in system logs) reported that they requested an unknown lease.  After several such requests the phones gave up and kept their old addresses.  Shouldn't dhcpd send a nack, and give the phones a valid address?  Are the phones broken, or is dhcpd broken, or am I broken?
