How to time limit a DHCP lease
Thinking my question falls into the grey area that may or may not be proper in the networking forum, so decided to try my luck in the server forum first.
I would like to be able to schedule a limit for an IP connection for my kid's computers/iPods. Since I know the MAC addresses of their various hardware items, is there a way to shut down their connectivity at a particular time via the DHCP server or perhaps a firewall rule?
Running Ubuntu 10.04 and Shorewall is being used for the firewall.
