How would i create a Web Portal for ppl who signon to my WiFi Signal?

Question

I have a wifi connection in my house, problem is I have every hotspot junkie sitting outside across the street at the autozone using my connection. now I know I could just make it a secured connection no big deal but when I went to Mcdonalds the other day and used their wifi inspiraiton hit. I want them to access a webpage that I set up and cannot go anywhere else unless they pay me $2.oo an hour how would I do it? Im familiar with HTMl and PHP just the mechanics of not letting them navigate is what is getting me.

Answer 1

Unless you have a business license, this would not be a good idea. Basically, you make all port 80 requests redirect to a page you create, unless a verified session has been created (via cookie, or php session variables).

However, if your network is not secured in the first place, good luck keeping it up.

Answer 2

Gilly is basically right. You'd need more/better hardware than what you have right now. You'd have route all port 80 requests to a http site that you designate, then use that as a pay-per-use portal. That would take some serious programming skill, and the freeloaders just wouldn't pay. All that effort would be wasted. In fact, if you had an unsecured hotspot that redirected like that, you'd eventually tick off someone who knew what he was doing. He'd then hack your network and trash your systems just to "get even" for you trying to charge for what he thinks should be free. Then, once you recovered, he'd do it again. Since it only takes about 30 seconds to hack WEP security, he'd trash you again and again till he got bored.
