LARTC - Oct 2005 - How would this help my LAN / network

HI all

I just came across one of the threads on the LARTC.
In the thread it had this.

So my question is, for the following rules, would these increase my browsing /
traffic, and if so, how.

iptables -t mangle -A PREROUTING -p tcp -m tcp --tcp-flags SYN,RST,ACK ACK -m
length --length 0:128 -j TOS --set-tos Minimize-Delay
iptables -t mangle -A PREROUTING -p tcp -m tcp --tcp-flags SYN,RST,ACK ACK -m
length --length 128: -j TOS --set-tos Maximize-Throughput
iptables -t mangle -A PREROUTING -p tcp -m tcp --sport 20 -j TOS --set-tos
Maximize-Throughput
iptables -t mangle -A PREROUTING -p tcp -m tcp --sport 21 -j TOS --set-tos
Minimize-Delay
iptables -t mangle -A PREROUTING -p tcp -m tcp --sport 22 -j TOS --set-tos
Minimize-Delay
iptables -t mangle -A PREROUTING -p udp -m udp --sport 53 -j TOS --set-tos
Maximize-Throughput
iptables -t mangle -A PREROUTING -p tcp -m tcp --sport 80 -j TOS --set-tos
Maximize-Throughput
iptables -t mangle -A PREROUTING -p udp -m udp --sport 123 -j TOS --set-tos
Minimize-Delay

Out of interest, Can I use this on the FORWARD.
If so, would it be best in the PREROUTING, or the FORWARD.
Baring in mind that this is for a natting FW.

I have a private LAN, behind the FW, I basically would likes to try and speed
things up for my users.

If someone would take the time to briefly explain this to me, I would be most
grateful.

Kind Regards

I use something similar in my script... but it''s useless to change TOS
by
itself, because this setting is pretty much ignored everywhere. So 
changing TOS alone won''t do anything.

However, if you''re using this together with some scheduler that uses
the
TOS setting to classify packets (like PRIO qdisc), it can for example 
affect the order in which the packets are going out the net.
