Hello ! I am on the road to learn to protect my server and I want to suppress the unrequested ARPs, coming from the WAN side of my linux router from the KabelBW network. I am using debian squeeze and I installed ebtables successfully [ebtables v2.0.9-2]. I just started with a simple rule: ebtables -t filter -A INPUT -i eth1 -d ff:ff:ff:ff:ff:ff -j CONTINUE This is simply to allow me to see the counters. But nothing is shown: >>> [/ops/fw]ebtables -L --Lc Bridge table: filter Bridge chain: INPUT, entries: 1, policy: ACCEPT -d Broadcast -i eth1 -j CONTINUE , pcnt = 0 -- bcnt = 0 Bridge chain: FORWARD, entries: 1, policy: ACCEPT -p ARP -i eth1 -j DROP , pcnt = 0 -- bcnt = 0 Bridge chain: OUTPUT, entries: 0, policy: ACCEPT <<< I am running tcpdump and I am seeing a lot of this packets with the dest address like in the rule above. I do not have a separate bridge configured, just use my WAN interface. Any help would be really great! Thanks anyway and best regards, Manfred -- 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
