I have quite complex setup managing two external interfaces with many classes and over 350 users. IMQ works reliable and stable :) I tried to experiment and to direct flow to IMQ I used rule in mangle table but in FORWARD chain like following: $IPTABLES -t mangle -I FORWARD 1 -i $ext_if1 -o $internal_iface -j IMQ --todev 0 It works fine. I also tried to direct local destined traffic via following rule to have opportunity to run some local services and not disturb shaping policy.. $IPTABLES -t mangle -A INPUT -i $external_iface -j IMQ --todev 0 I couldnt use PREROUTING to achieve this result due to my box is doing NAT and I have some classes/filters related to local destination IPs. It looks that second [INPUT] chain have some impact on traffic shaping but it was very strange. Then I put that rule my interactive traffic becomes very poor [NAT box didnt generate any traffic itself]. Normal situation RTT was about 60ms but when launched rule in "-t mangle INPUT" average RTT jumped to 500 or even 1000 ! OK, thats all my report today :) Going to play more with QL IMQ driver.
