I was running into a similar situation, and if you hand load the ebtables module you can use it from the command line (at least now, i realize this is an old post)

I got a question about the interface though. The ‘Apply To: Routed or bridged interfaces’ only comes up for the FORWARD chain. Can this be applied to the INPUT and OUTPUT chains as well? And if it was, would it use some ebtables module to be able to block things like DHCP with the interface?

because while you can add a rule with iptables to the input chain, to block DHCP, and it will get triggered. it wont work, because dhcpd and iptables are basically operating at the same layer.
