 It isn't as easy as that, that's my current setup, I have 2 subnets,
 10.2.0 and 192.168, I want the dhcp server to check the mac address and
 if it corresponds to the wireless card assign an ip on the 192 range.
 And obviously if it is the pcmcia card an ip on the 10 range.

 And the next step, update the dns record for the laptop.
