Ok, I will try this, I wanted to know if this iptable rule affects my other iptable rules in my firewall script, like I have a table for my NAT, does it matter if I put the mangle table before or after the NAT?


for example i have this rule in my nat to set up IPFORWARDING, masquerading and transparent proxying

iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE
iptables --append FORWARD --in-interface eth1 -j ACCEPT
iptables -t nat -A PREROUTING -p TCP --dport 80 -j REDIRECT  --to-port 3128

will adding the IMQ rule in my firewall script have any effect?

Yes, we are using IMQ also.
I use IMQ to limit incoming traffic using egress filter.
Once you use IMQ as follow, just use the new device (imq0) as you ussualy do
in your normal htb rule to eth0.


        modprobe imq numdevs=1
        ip link set imq0 up
        iptables -t mangle -F
        iptables -t mangle -A PREROUTING -i eth0 -j IMQ

Btw, since I'm not expert in Linux, maybe it is better to ask in lartc mailing
list. Thare is a lot of linux guru there :-)
Of course I will also help if I can.
