i need to serve DHCP requests for a given test tool tailored for a specific network hardware (hardware under test).
The testing tool (my server + simple netgear 5ports switch) seems to work as long as you pass one device at a time. When you start using 2 devices at the same time, both fail soon after the second device is plugged on the system.
Symptoms makes me think of two devices using the same IP address. Afterlooking in the wireshark trace, it seems to be exactly the case.
Those devices under test always show the same mac address : 4e:42:46:76:30:32 (NBFv02 in ascii). As a result, i think isc-dhcp-server observes that this mac adress has already been assigned a lease and serves it back to the other device.
How can i configure isc-dhcp-server so that it simply offers a new lease regardless of client mac adress?

thanks
[edit] i have made my own custom DHCP daemon. oh it does work. it offers leases regardless of client mac address. However, i seem to have other problems later on with ARP resolution. i am stuck
