Restrict static IPs (Only DHCP) on Debian Squeeze

How can i restrict access to the Internet for users with static IPs? Can i disable free dhcp leasing?

I'm running Debian Squeeze with dnsmasq as dhcp server. All users has their own ip, mapped to mac.

Thanks.

What is acting as a DHCP server? Are you asking how to disable DHCP? – terdon – 2013-04-27T14:58:07.890

dnsmasq is DHCP server. I'm asking how to disable free DHCP leasing. I want to give IPs only to allowed MACs. – IlyaGulya – 2013-04-27T15:08:37.963

Answers

use dnsmasq as DHCP server
List all your known devices in /etc/ethers
List all your static IPs in /etc/dnsmasq.d/dnsmasq.intranet.conf. Ref: DNSmasq Installation & Configuration
Use the following (in /etc/dnsmasq.d/dnsmasq.intranet.conf) to ignore any unknown clients

# Ignore any clients which are not specified in dhcp-host lines
# or /etc/ethers.
dhcp-ignore=tag:!known
