Hi Frank,

found something in huge net....could be usefull 4 yu....;=)

If more than one network interface is attached to the system, but the 
DHCP server should only be started on one of the interfaces, configure 
the DHCP server to start only on that device. In /etc/sysconfig/dhcpd, 
add the name of the interface to the list of DHCPDARGS:

# Command line options here
DHCPDARGS=eth0

regards from Hamburg
