[Askar Ali Khan]

hi all,

Heh lot reading today :) i duno why the guy started Netfiter Vs
Commercial thingy?
However I would love to add "Open Source is the clear winner
today..and tomm.. and also open source is what we "third world" can
afford :P.

Oops sorry, here is my question I just want to know im doing the below
on our company firewall, that Type of Service bit things.
My question is that
1) Is this beneficial for protocol like MSN and yahoo?

I check alot again and again sign in yahoo and msn, however im not
sure whether it give me a 4 to 5 second fast signin on yahoo and msn,
coz @ work we gota LAN where sometime these IM signin fast and
sometime take few seconds more then normal.

## For MSN thingy

Minimize-Delay
## For Yahoo thingy
iptables -I PREROUTING -t mangle -p tcp --dport 5000:5050 -j TOS
--set-tos Minimize-Delay
## For 443 thingy

Minimize-Delay
## For DNS thingy

You should ask you ISP.  It's a question to the routers between you and
the servers you connect to.  They have to look at the TOS-field and make
their routing-decision depend on this.  It could be used in some kind of
QoS to decide how to queue pakets.  From my experience most routers
ignore the TOS, but take a closer look to the amount of money the
customer pays and route in a linear dependence to this.  (YMMV)

HTH,
