The project is based on a host which acts as a layer 3 gateway between two subnets. The first subnet connect's the gateway to internet, second one contains the guest clients. Each client that want to connect to internet must pass the gateway. On the gateway itself traffic coming from client net (guestnet) will be firewalled. That means that each client which is not known or not activated by a valid voucher will be forwarded automatically to the registration website located on the gateway itself. Each client that is/was activated and his voucher is still valid can pass the gateway and connect to the internet. The central token to identify and handle the traffic of each client is their worldwide unique mac address.
