freeradius clients are only pingable

Dear all, I am using freeradius on the server and i installed also a zoneminder, the cam's are getting auth by MAC and that works fine. no i am trying to let zm control the cams but it seems that it can't because some routing issue. i tried then to log to the server and http another ubuntu laptop and can't still open the page. what is the missing with me ? *Best regards,* *Mohammed Farouk*
