http://wiki.nix.hu/cgi-bin/twiki/view/IMQ/OtherImqDocs
http://www.linuximq.net/

but i didn't find the answer.
Now expamle
i'm geting up imq dev 0
ip link imq0 up
look at schematic here:
http://www.docum.org/docum.org/kptd/
in iptables i'm making:
iptables -t mangle -A PREROUTING -p all -j IMQ --todev 0
now the packiet is pushed to IMQ0
and now what is the way of the packet?

1) PREROUTING
2) conntrack, mangle
3) IMQ
3.1) PREROUTING
3.2) FORWARD
3.3) POSTROUTING
4) PREROUTING nat
5) FORWARD
6) POSTROUTING

is this correct?

OR:
1) PREROUTING
2) conntrack, mangle
3) IMQ
3.1) PREROUTING
3.2) FORWARD
3.3) POSTROUTING
4) FORWARD
