How I make in the IPTABLES it:

How I make it????

Here's how I log (and drop) all my low ports.

$IPTABLES -A INPUT -p tcp -i eth0 --dport 1:1024 -j LOG --log-level info --log-prefix "TCP DROP "
$IPTABLES -A INPUT -p tcp --dport 1:1024 -j DROP
$IPTABLES -A INPUT -p udp -i eth0 --dport 1:1024 -j LOG --log-level info --log-prefix "UDP DROP "
$IPTABLES -A INPUT -p udp --dport 1:1024 -j DROP

Here's my chain for blocked specific IP's...
$IPTABLES -N BlockedIP
$IPTABLES -A BlockedIP -j LOG --log-level info --log-prefix "Blocked_IP"
$IPTABLES -A BlockedIP -j DROP

Search on google for some iptables howto's and tutorials.
