Configure Aironet 1100 with static ip and as a DHCP server

While looking at cisco.com to find som documentation for this, anybody done
this configuration:
The AP is connected to an LAN with internet access thru its ethernetport. I
want to assign a static ip for the AP, but also wants it to act as a DHCP
server.
I want the Ap to assign ip addresses in a drifferent range than the LAN
connection. Something like this:

LAN with internetaccess 192.168.0.0 ..
