Linux Ethernet Bridging - Apr 2007 - [Bridge] htb accounting on bridge interface

Hi!

I am using a linux bridge as an internet gateway. I have eth0 as the external
interface, eth1 and
tap0 (OpenVPN) bridged together (br0). I was trying to make a seamless
accounting for br0 with tc
and htb (hand made scripts). The accounting is not working for br0, instead I
have to make
accounting on eth1 and tap0.
Is this the right way? I only want to limit the trafic between eth1 and eth0 +
viceversa and tap0
and eth + viceversa.

Thanks in advance,
Ady Deac

The bridge interface itself normally doesn't have an output queue for
queuing stuff to hang off because it is not limited by a single hardware
device. You can place a queue there with traffic control tools, but
it would only make sense if doing rate control.

Also br0 is only invoked for locally generated packets. If you are a gateway,
all traffic passing through never touches the br0 pseudo-interface.
