with recent kernels, I have this problem:
Bugreports to netfilter-devel please.
kernel: physdev match: using --physdev-out in the OUTPUT, FORWARD and
POSTROUTING chains for non-bridged traffic is not supported anymore.
What does "non-bridged" in this context mean?? If it means rules (or
traffic) that goes over the INPUT our OUTPUT chain, I do not understand,
why my rule set causes this message to appers a thousand times.
Here's all my rules with --physdev-out:
arthur: ~ # grep physdev-out /etc/init.d/firewall
$IPTABLES -A FORWARD -o $BR_INT -m physdev --physdev-out $IF_INT -i $IF_EXT -d $localnet -s $Any -m state --state ESTABLISHED,RELATED -j ACCEPT

$IPTABLES -A FORWARD -i $BR_GUEST -o $BR_INT -m physdev --physdev-out $IF_INT -p tcp --dport ssh -j ACCEPT
$IPTABLES -A FORWARD -i $BR_GUEST -o $BR_INT -m physdev --physdev-out $IF_INT -p tcp --dport 30022 -j ACCEPT

Where:
BR_INT="br-intern"
BR_GUEST="br-guest"
IF_EXT="eth0"
IF_INT="eth1"
IF_DMZ="vlan3"
You see, I use --physdev-out only in the FORWARD with bridged traffic,
because the Interfaces given with -i or -i in these rules are always
bridges (br-intern or br-guest).
Why do I get thousands of these error messages?
Try adding "--physdev-is-bridged" to your rules. Without that the kernel
is not able to tell whether they apply only to bridged packets or also
to forwarded or locally generated ones.
Suggestions how to improve this are welcome.
