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.
