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 ip addr 1: lo: <LOOPBACK> mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: tunl0: <NOARP> mtu 1480 qdisc noop link/ipip 0.0.0.0 brd 0.0.0.0 3: gre0: <NOARP> mtu 1476 qdisc noop link/gre 0.0.0.0 brd 0.0.0.0 10: eth0: <BROADCAST,MULTICAST,PROMISC,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:07:d9:0d:67:5a brd ff:ff:ff:ff:ff:ff 11: eth1: <BROADCAST,MULTICAST,PROMISC,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:07:d9:0d:67:03 brd ff:ff:ff:ff:ff:ff 12: br0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue link/ether 00:07:d9:0d:67:03 brd ff:ff:ff:ff:ff:ff inet 10.10.5.2/24 brd 10.10.5.255 scope global br0 iptables -L -nvx Chain INPUT (policy ACCEPT 4484 packets, 330543 bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 4105 packets, 2046064 bytes) pkts bytes target prot opt in out source destination
Bridged traffic is not seen by iptables. You need ebtables instead.
