|At my school, they have an open wireless network set up. If you connect, all ports are blocked except 80 and if you attempt to visit any website, you are automatically redirected to a single site. At this site, you can enter a username and password. When you enter valid credentials, you are given full access to the internet.|
I want to set this up on my private LAN at home.
I have a wireless router and a linux server. I'm assuming I would want to connect my linux server directly to the internet, then share that connection with the router, but where would I go from there? How do I restrict the traffic going through the server and then allow full access to particular clients on the lan?
Any advice would be greatly appreciated, thanks.
