I'm actually trying to develop a public wireless network (not business, just for educational purposes, I am studying computer science...). But I am lacking the required knowledge to acheive this goal (I am usually more into programming than network management [love Stack Overflow ;-)]).
What I want to do exactly is just like lot of cities/schools's public networks, where every adress is redirected to a login page before being able to access the internet.
My current setup is made like this: I have my Internet connected to a wired router. This router is connected to a Switch. My personal computers are connected to this switch. I have an IIS server connected to the router.
I have a Wireless Access Point, but I don't know how to set it up to redirect the incoming IPs to my IIS. Basically I want to block all the Internet and redirect non-local requests to my local IIS (for WiFi users only, LAN should have Internet).
I thought maybe installing a DNS on my server and setting it as primary DNS in the router. Or maybe connecting WiFi to the server (with a second Network Adapter) and redirecting via firewall/proxy, but I don't know if these would theorically work, before jumping into learning how to set up one of these options...
Any help greatly appreciated!
