Autoip on DHCP server

Hi,

I am running debian on the BBB. I have the device setup as a DHCP server on 192.168.5.1/255.255.255.0

One of the devices that connect need to be able to fall back to connecting to the BBB via autoip should it not get an IP address from the dnsmasq.

I have installed avahi-autoipd but I am not sure how to fit everything together.

As my BBB eth0 already has an ip address off 192.168.5.1 (as I set it up being the server) how does it also provide an autoip address of 169.254.something.

Hope some one can help
