If have just booted into 2.6.0-test4. Unplugging works, but the console is flooded with: last-F IN=br0 OUT=br0 PHYSIN=eth1 PHYSOUT=eth0 SRC=10.96.96.25 DST=10.96.96.255 [last-F ist the last rule in my FORWARDING iptable and does log+drop] Obviously I must allow forwarding br0 <=> br0. While I am writing this the counter on the FORWARDING rule -i br0 -o br0 -j ACCEPT has reaches 2000+ packets with eth0 unplugged and the kernel ist still running. In both 2.4.22 and 2.6.0-test4 all of netfilter and advanced routing ist set to M. In 2.6.0-test4 this includes ebtables. Hope that helps Hannes
