Topic: Chillispot imbedded in StarOS

I have a couple of configuration issues in getting the Chillispot based StarOS Hotspot to work.
Has anyone implemented the StarOS v3 hotspot to use MAC authentication as well as allow unknown MACs to connect?
I need to have then known MACs authenticate via Radius. Radius returns a Framed-IP which then needs to be given to the device.  These will be in the range x.y.z.0 - x.y.z.127.  The unknown MACs need to have Chillispot return an address in the range x.y.z.128 - x.y.z.254.
Any suggestions on how to do this, either directly in Chillispot or in StarOS?
