Hello people, Im relatively new to the ebtables + iptables firewalling architecture. I have read the ebtables and iptables firewall interaction document and also seen the GIF specified at the end of the document. For those unfamiliar with it, here are the links to the same: http://ebtables.sourceforge.net/br_fw_ia/br_fw_ia.html for the document and http://ebtables.sourceforge.net/br_fw_ia/PacketFlow.png for the picture. Im trying to understand what happens to a packet which is DROPped in the BROUTING chain of the broute table. If I have understood correctly from the document above, it goes to L3 where the routing subsystem can decide where to send the packet to depending on L3 information in it isn't it? So i'm assuming that the first place it should be visible should be the PREROUTING chain of the mangle table isn't it? But I tried with a LOG target rule matching the criteria I used in constructing the DROP target in the broute table's BROUTING chain. And then after that I checked the packet counters for both the rules viz. the one in the BROUTING chain and the one in the PREROUTING chain of the mangle table. The packet did hit the first rule and it is dropped. I cannot see it on br0, the bridge interface too. But the packet count in the latter rule is 0 which means that the packet didnt arrive in the mangle table's PREhttp://ebtables.sourceforge.net/br_fw_ia/PacketFlow.pngROUTING chain. But this behavior is contrary to what the GIF above shows. Im rather confused. Please do shed some light on it if people have had similar experiences before. I am keen to hear from you, Regards, Aijaz Baig. -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
