You want CONFIG_BRIDGE_NETFILTER=y, this makes iptabes see bridged packets.
Additionally you need CONFIG_NETFILTER_XT_MATCH_PHYSDEV=y, that allows
matching on the physical device name for bridged packets. That way you
can filter by domain (because each domain has its own virtual bridge
port) instead of ip/mac address.
