Hi,

with this setup, you will have to activate the "Internet connection sharing". 
You should be able to setup this quite easily with the graphical network 
configuration frontend provided by Mandrake. With this setup, Mandrake will 
automatically configure to activate NAT and also install a DHCP server on 
your wireless interface.

On your Windows machine, you should activate the "Obtain an IP address 
automatically" on your wireless device. This setting will make Windows to use 
DHCP to automatically configure itself correctly.
