IP Table help, Droping entire 200 block of ip's?
 
Hi All

I need a little help with iptables.
I want to block all of the Brazil ip addresses, I understand they are in the 200 block.

Is this the correct way to block the 200?
Code:
iptables -A INPUT -s 200.* -j DROP

Any help greatly appreciated :)

No, iptables doesn't accept wildcards. Try using the CIDR nomenclature instead:

iptables -A INPUT -s 200.0.0.0/8 -j DROP
