Subject: drop dhcp request from a particular mac address, after a dhcp relay
Date: Wed, 10 Mar 2010 06:30:52 -0800 (PST)	[thread overview]
Message-ID: <418652.3218.qm@web31505.mail.mud.yahoo.com> (raw)


I would like to inhibit a dhcp request from a particular mac address, on the dhcp server.

If the client is directly LAN connected, I would suppose the following will work :-

iptables ....... -m mac --mac-source 

But to add a twist to the problem, the machine which must be blocked from obtaining a DHCP IP is connected to a DHCP relay, and therefore, the dhcp server is seeing only the mac adddress of the relay. Can this be accomplished with iptables ? 

Is there a match which works something like this :-

  iptables ..... -m bootp --mac-source 00:08:a1:ab:75:d1 -j DROP ?

Well, if 'iptables' can't serve the purpose, how about ebtables ?

Regards.
