Hello, I know because I see no increment in the counters and I have a packet capture running. I think your explanation, about what the FORWARD chain can see, answers my question. In my case the gateway is not a bridge, so it is normal that I don't see hits there. Thanks, Alexis. ________________________________________ From: Pascal Hambourg <pascal@xxxxxxxxxxxxxxx> Sent: December-24-13 13:24 To: Alexis Salinas Cc: netfilter@xxxxxxxxxxxxxxx Subject: Re: arptables FORWARD chain not working Hello, Alexis Salinas a écrit : > I tried using arptables on a linux internet gateway to filter out > packets that have the source MAC address of the internet connected > interface but not its IP address (see below). > I didn't get any hits, although I now there were packets matching the > rule.

ARP packets generated by the host go through the OUTPUT chain. The FORWARD chain sees only bridged ARP packets, which are received but not generated by the host. Is your gateway acting as a bridge ? -- 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
