win4lin and dhcp

[Maupertuis Jean]

i install Win4lin and want to communicate( internet) using VNET.
So  try run dhcpd but i don't know what to put in the dhcpd.conf because the 
man page is very esoteric for a user (not a network manager).
I try to use the configuration file given as sample with the rpmw with no 
success. dhpcd tell thre is no subnet declaration for start (0.0.0.0)and 
isnot configured to lsten on any interfaces.
Perhaps someone succeeds to use wn4lin with dhcp and can help me.
