Hey, The /24 is incorrect, the last number must be a 0 like 69.212.12.0/24 for a 256 ip block starting from 69.212.12.0 to 69.212.12.255
I'd do this way: /sbin/iptables -A INPUT -s 69.212.12.0/24 <http://69.212.12.76/24> -j DROP /sbin/iptables -A INPUT -s 69.212.12.76 <http://69.212.12.76/32> -j DROP The /32 is indeed only for that ip so it's really pointless to add the /32 on there. Fix the /24 and then you're ready to roll. Bryan Fri, Jan 11, 2013 at 11:32 AM, Steve Wolf <[email protected]> wrote: > I have taken a course on IP numbers etc. but I dont recall.
