Hi Joerg,
you could try to bind your dhcpd on a pseudo bridge interface and filter
with ebtables. The syntax is quite the same as the usage of iptables...

Hello all,
I was seriously puzzled why iptables could not stop dhcp requests from reaching ISC dhcpd. Now I found the reason: instead of listening on a UDP socket dhcpd installs a LPF similar to tcpdump or ethereal. This bypasses the protection from the firewall. What can I do to regain that protection?
