Shorewall users - Dec 2002 - Mark ACKs

Hi all
 
I have a question:
 
How can I add this rule in shorewall?:
 
Iptables -A POSTROUTING -t mangle -o ppp0 -p tcp -m length -length :64
-j MARK -set-mark 10
 
TiA

While the subject of your post says "Mark ACKs", the rule above does 
something different; it is marking all short packets (which will include 
ACK packets). You can still place that rule in /etc/shorewall/start 
replacing the "Iptables" (Sic) with "run_iptables".

Looks like you are installing someone''s traffic-shaping script. I 
personally use Wondershaper which gives priority to short packets without 
having use any iptables commands - there''s a link from my traffic 
control/shaping page.
