+
+Why does arptables have 2 chains on a 2.4 kernel and 3 chains +on a 2.6 kernel? +
+
+The 2.4 kernel doesn't have the arptables FORWARD chain as 2.4 +kernels can't filter bridged ARP traffic. +
+
+When is the bridged ARP traffic seen by arptables? +
+
+The artables FORWARD chain sees all ARP packets that are being +bridged, it sees no other traffic. +
+
+What about ARP packets that arrive through a bridge port and +are delivered to the bridge's local ARP stack? +
+
+They are seen in the arptables INPUT chain and have as input +device the logical bridge device, unless you broute them +using ebtables. Brouted packets will have the physical bridge +port as input device. +
+
+What about locally generated ARP packets that leave the bridge +through a logical bridge device? +
+
+They are seen in the arptables OUTPUT chain and have as output +device the logical bridge device. +
