HOLD ON,
This creates the following:
chain INPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere
DROP       all  --  202.71.136.166       anywhere

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere

Looking at the first and last rule displayed here, dosn't this have the effect 
of negating everything else?
Eg: Allow all, from anywhere to anywhere....

Am I missing something?
