Im looking for a solutions to set-up free wifi hot spot, but not completely open - i want to give access to all customers via paper coupons/codes. Like, each code is valid for 3 hours of surfing internet. It is kinda complicated, so i`ll try to explain the idea by steps:
- Client come to a place (coffee shop, etc) and ask for the access code
- Connect to unsecured wireless network
- Redirect to gateway login page until client enter his access code (if not - disconnect in 3-5 mins)
- Assign the access code to client`s MAC address and IP address
- Disconnect client on code expiration time
Another problem is: how to control the traffic on regular wifi access point? I know, it is easy to do with server gateway, but the original requirement is based on basic wifi routers.
I understand, this is really specific project, so i wanna know, which systems can fit this requirements the best ? Any helpful ideas ?
