Clonezilla-SE with another DHCP Server in LAN

I want to install Clonezilla-Server(192.168.1.100) in a network that already have a DHCP Server (dd-wrt with dnsmasq - 192.168.1.1). I've installed Clonezilla-SE on ubuntu Server 10.10, once installed and configured Clonezilla Server i've removed the DHCP-Server and set pxe server address in dnsmasq configuration on DHCP Server :

dhcp-boot=pxelinux.0,,192.168.1.100

When i try to start from PXE a Computer in the network clonezilla start, but give me an error that the ipddress of the machine is not given by the clonezilla server and can't continue ... Someone has already tried to configure Clonezilla-SE in a similar enviroment?

Is there some configuration on DRBL server of Clonezilla that i need to do ?

To make the netboot image accept any dhcp, run this command on the DRBL server: /opt/drbl/sbin/mknic-nbi -c n

The caveat is that DRBL clients may fall back to assuming that the NFS shares are on the gateway address given out by DHCP. In a nutshell, DRBL assumes that your netmask is 255.255.255.0 and falls back otherwise. You can change this assumption by editing the client init script directly.
