Integration with CISCO Router for PEAP requests

How can I configure FreeRADIUS to work with a CISCO Router and a captive portal in the following case... 1. User tries to access WiFi network with good user and wrong password 2. FreeRADIUS should send Access-Accept with Filter-Id set to portal redirect policy and not Access-Reject 3. User is presented login page, bla, bla, bla My problem is that i have to send an Access-Accept on failed login for PEAP (For TTLS I've managed to do it from config, but this is another story) Thanks in advance, Andras
