OK, found the answer.
This is if you wish to block an internet ip range from accessing anything from your IP.
edit /etc/rc.d/rc.firewall.up, and immediately after the line containing:
iptables -P OUTPUT ACCEPT
iptables -A INPUT -p all -s a.0.0.0/8 -j DROP
where a. is the range you want to block
iptables -A INPUT -p all -s 188.8.131.52/8 -j DROP
