I want to implement this so that only one machine should be able to use
internet (the machine which I hv configured to use internet ) and not others
which may be behind it. With the implementaion of iptables/ipchains policy
on my gateway i am able to define that only that machine can use internet
and not others but the user on that m/c can load some proxy on his machine
and allow other also to use internet, which i want to block .
