i have a minor problem here. I have chillispot+freeradius+mysql installed successfully with mac address authentication. the problem is users need to renew/released their IP before they begin to use the internet.
If im not mistaken, this steps is required by chillispot to get the mac address and then validate it to freeradius.

is it possible to auth users without force the users to release/renew their ip ? and how ?

thanks
