How to manage filtering by MAC in Ubuntu?

Scenario:

Ubuntu DHCP is configured and working (network 192.168.1.0)

a) Laptop 1 is set in configuration on Ubuntu as static IP
Laptop 1 is configured for automatic IP and when is connected to server everything works.
I'm taking laptop 2 which is configured as static IP 192.168.1.10 and his configuration is not set in Ubuntu dhcpd.conf
After laptop 2 is connected internet working.

It is possible to do MAC filtering which disallow to connect PCs with address IP set as static but MAC address is not configured in Ubuntu (something like: intruder in network)?
