Hello

I try to setup QOS into bridge context. But this not very clear for me
So assuming that   :
    eth1 = LAN
    eth0 = INTERNET

br0       Link encap:Ethernet  HWaddr 00:30:48:87:99:28
          inet addr:xxx.xxx.xxx.xxx  Bcast:xxx.xxx.xxx.xxx 
Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:5697373 errors:0 dropped:0 overruns:0 frame:0
          TX packets:164166 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:320113723 (305.2 MiB)  TX bytes:35162676 (33.5 MiB)

eth0      Link encap:Ethernet  HWaddr 00:30:48:87:99:28
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:12797225 errors:0 dropped:0 overruns:0 frame:0
          TX packets:164149 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100
          RX bytes:1045689736 (997.2 MiB)  TX bytes:35893643 (34.2 MiB)
          Base address:0xc000 Memory:f2000000-f2020000

eth1      Link encap:Ethernet  HWaddr 00:30:48:87:99:29
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
          Base address:0xd100 Memory:f1000000-f1020000

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:20 errors:0 dropped:0 overruns:0 frame:0
          TX packets:20 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:1480 (1.4 KiB)  TX bytes:1480 (1.4 KiB)

I'm seen somewhere that eth0, eth1 should be set in promisc mode and
that the network script to this for me ...
Bun in fact,  I'm not sure that my eth0 and eth1 are in promisc mode  ...

For the outgoing I've made an iptables user table to redirect outbound
traffic
If I put  eth0  instead of br0 as outgoing interface the traffic is not
shapped ???

iptables -t mangle -N OUT
iptables -t mangle -A POSTROUTING -j LOG
iptables -t mangle -A POSTROUTING -o br0 -j OUT

In my log I've got this ...

Dec 11 04:07:02 gestor1 kernel: IN= OUT=br0 SRC=xxx.xxx.xxx.xxx
DST=xxx.xxx.xxx.xxx

Logically, due to the same problem I can't do something like this to
shape the inboud traffic :

#ip link set imq0 up
#iptables -t mangle -A POSTROUTING -o eth1 -j IMQ --todev 0

Regards

Thanks for your help
