Ok here is a little background. We have about 400 people on our network and it is routed through a linux box to a DS3 connection. Before they are able to get online, they are required to register their computer and then a php script allows them access once they register their MAC address with us. Is there a way to force the users of our network to be redirected to our intranet registration page no matter what site they type in the address bar if they have not registered. This is so it makes it easy for people that forget they have to register. I know it can be done, because the university I go to does it for their wireless access where it will redirect you to a login page no matter what page you request. I just don't know if linux can do it. Thanks.
