Just for the record, as I'm the maintainer of ebtables and the bridge-nf code I can safely say that these statements above are not correct. ebtables is there to filter on non-IP stuff, more specifically the Ethernet header. In 2.6 or in a patched (with the bridge-nf patch) 2.4 kernel, the PREROUTING/FORWARD/POSTROUTING iptables chains see bridged traffic. This is therefore different than the behaviour with the old patch vs 2.2 for ipchains. Anyone interested can go to ebtables.sourceforge.net, the working of iptables on a bridge is explained there in detail. Please update your documentation. cheers, Bart
