iptables and bridging

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Folks,

Am I correct in saying that in a setup where multiple interfaces are connected to a Linux bridge, iptables (using -m physdev) can stop non-broadcast traffic appearing on the wrong interface? I know generally that the bridge will act like a switch and only send frames to the correct interface, however this is not always the case (during learning, for example, where it acts like a hub for a second or two)

Thanks
