Hi All,
Please to advice me. I become crazy because i cannot find where can be
problem. Obviously i miss something, but what ?
I have Linux router for traffic control / ~400 users , 100 mbit bandwidth /
. evereting was great until i try to implement IMQ for ingress shaping.
Problem that i have is when i start follow iptables rule
iptables -t mangle -A PREROUTING -i eth1 -j IMQ --todev 0
without any TC started all traffic slow down and Linux increase system load
average.
