Hi all, i have a linux box with three ethernet card. I want to bridge eth0 with eth2 and to have eth1 like a DMZ. Before, i was using linux-2.4.27 with iptables-1.2.11 and bridge patch. It was working very weel. Now, i have updating my kernel to 2.6.21.5 and iptables to version 1.3.7 and it does not work anymore. In my /var/log/message i can read some : kernel: physdev match: using --physdev-out in the OUTPUT, FORWARD and POSTROUTING chains for non-bridged traffic is not supported anymore. What does it means ? I can't do what i want with iptables? I must use ebtables ? Thanks a lot for your answer. Ludovic MARCILLY
