Hi

I think it would be easier to make this at firewall level. For
example, assign an IP address range from 192.168.1.10 to 192.168.1.50
to unregistered addresses, and at your gateway, use iptables to block
addresses in that range from passing through. When you register your
client, assign an ip outside that range. You could make this based on
ports too.
