Hi everybody, I have a strange problem. I recently found IMQ dummy device and I was anxious to test this on my router. I have the following configuration: iptables -t mangle -A PREROUTING -i eth0 -m mark --mark 0 -d $MY_NET -j IMQ --todev 0 iptables -t mangle -A POSTROUTING -o eth0 -m mark --mark 0 -s $MY_NET -j IMQ --todev 1 insmod imq tc qdisc add dev imq0 root handle 1: htb default fff tc qdisc add dev imq1 root handle 1: htb default fff tc class add dev imq0 parent 1:0 classid 1:1 htb rate 192Kbit ... tc filter add dev imq0 parent 1:0 protocol ip prio 100 u32 match ip src... bla bla bla ip link set imq0 up; ip link set imq1 up The problem is that when I run this script, those packets that are routed via imq* (0 for in and 1 for out) are slowed down to ridiculous speeds (1kbit or less for a 64kbit class for eg.) I read about some bugs that lies in IMQ code but I also read about crashes related to this bugs and this is not my case. Could anyone help me pls? I must finish this script till monday. Could it be usage of u32 filters? But still I see that packets are getting to the right classes. Thanks, Alin Nastac
