[LARTC] Incoming trafic shaping (depending on src IP)

[Spyou spyou@club-internet.fr]

<PRE>
Hi there,


i'm trying to shape incoming trafic on my linux box.

I want it to depend on the source IP adress of the packets (in fact, i got 
a VPN on an ADSL link and wanted to get at least/max 64Kbit/s for the VPN)

So i tried this :

tc qdisc add dev ppp0 root handle 1:0 cbq bandwidth 512Kbit avpkt 1000 cell 8
tc class add dev ppp0 parent 1:0 classid 1:1 cbq bandwidth 512Kbit rate 
512Kbit weight 50Kbit prio 8 allot 1514 cell 8 maxburst 20 avpkt 1000
tc class add dev ppp0 parent 1:1 classid 1:10 cbq bandwidth 512Kbit rate 
64Kbit weight 6Kbit prio 8 allot 1514 cell 8 maxburst 20 avpkt 1000 bounded 
isolated
tc qdisc add dev ppp0 parent 1:10 tbf rate 64Kbit buffer 10Kb/8 limit 15Kb 
mtu 1500
tc filter add dev ppp0 parent 1:0 protocol ip prio 100 u32 match ip src 
&lt;the SRC IP of my VPN&gt; flowid 1:10

Okay, so, with this, packets comming trought ppp0 and from &lt;the SRC IP of 
my VPN&gt; should be shaped at 64Kbit/s, right ?

Where's my error ? Is there something more simple (eg. with iptables and 
packet marking ?)


thx for help :)
