Bridged traffic is not seen by iptables. You need ebtables instead.

Subject: Bridge and iptables
Hi,
I am using linux kernle-2.6.15, iptables-1.4 and bridge-utils-1.4.
Everything intslled without any issue and i am able to enable the
bridge and traffic is also flowing without any issue.
But i did not see any traffic on the iptables forward chain due to
which i am not able to control the traffic.
Do i requie enable anything more to make the traffic pass through
iptables forward chain.
Please look into the configuration
