wir haben einen Server mit 6 Nic am Start, wobei Nic 2 + 3 als Bridge Br0 laufen sollen.

Wenn ich mir mit tcpdump eth2 und eth3 ansehe, sehe ich jedoch nicht den selben Traffic. Ich bin davon ausgegangen, das der Traffic 1zu1 weitergleitet wird. Wir wollen später über IPtables den Trafic zwischen eth2 und eth3 Filtern (FW/iptables). Anbei meine Config, für den goldenen Tipp wäre ich dankbar.
