Redirecting Reject Request To Webpage

Hi FreeRadius List Members, Thanks for all the support ever. i am having difficulty to understand something, i need help. i am able to configure mac authentication base on the following logic. it Works !! username="<mac address>";attribute="Auth-Type";op=":=";value="Accept" username="<mac address>";attribute="Auth-Type";op=":=";value="Reject" *Question:* Redirecting Reject Request To Webpage For example, a customer would get reject from FR due to non payment. but at this stage customer do not know, what is happening. Why internet in down. We want the request to redirected to a web page that will display the cause of disconnection. Thanks RM --
