[LARTC] Matching interface using U32(?)

[Nataniel Klug <nata@cnett.com.br>]

    Hello all,

    I am trying to make a little bit more complex QoS/Shapping form and 
I need to shape a PPPoE conection that I serve to my clients. So this is 
the scope:

client connects using pppoe so it gets an IP address (from pppoe pool) 
and open an interface into my linux box
interface for this client is ppp0
client has got an ip 1.1.1.2/32 and it is poiting to pppoe-server 1.1.1.1

    So, if i want to shape download for this client its really easy and 
I make a htb rule that shapes all traffic into ppp0... My problem is 
when I have to shape upload traffic. All my traffic goes for eth0 to the 
world. I tryed to make this rule:

$TC class add dev eth0 parent 1:1 classid 1:500 htb rate 200Kbit ceil 
200Kbit
$TC filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip src 
1.1.1.2/32 flowid 1:500

    But this rule is not matching the upload connection. If i put the 
same rule to an IP (i set an ip into client) this rule works but into 
pppoe conection it did not work properly.

    Someone has some tip to match the interface that the conection is 
coming from? Like I wanna match all traffic coming from ppp0 and going 
throw eth0 to be shapped?! There is anyway to make this work?

Att,

Nataniel Klug
