Right. Think of this question another way: "On which member interface in the bridge is this MAC address reachable?" It's a bridging issue, nothing to do with VLANs. But depending on what you want to be able to do with this information I may have a simple answer for you anyway. :) You can use ebtables to make rules even inside a bridge. These rules can mark packets, and the mark can be read in iptables. If you want userspace accounting or logging, I guess ebtables rules with a target of netlink or even syslog would be the easiest solution. //Peter
