$IPT -t filter -A INPUT -m state --state INVALID -j LOG --log-prefix 
"INVALID input: " --log-tcp-options --log-ip-options

$IPT -N SSH_Brute_Force
$IPT -A INPUT -p tcp --dport 22 -m state --state NEW -m recent --name

$IPT -A SSH_Brute_Force -j LOG --log-prefix "SSH Brute Force Attempt:  "
$IPT -A SSH_Brute_Force -p tcp -j DROP

$IPT -t filter -A INPUT -p tcp --dport 10000 -m state --state NEW -j ACCEPT
$IPT -t filter -A INPUT -p tcp --dport 113 -j REJECT --reject-with 
icmp-host-unreachable
$IPT -t filter -A INPUT -p tcp -m multiport --dport 135,137,139 -j DROP
$IPT -t filter -A INPUT -p icmp --icmp-type source-quench -j ACCEPT
$IPT -t filter -A INPUT -p icmp --icmp-type parameter-problem -j ACCEPT
$IPT -t filter -A INPUT -p icmp --icmp-type destination-unreachable -j

$IPT -t filter -A INPUT -p icmp --icmp-type time-exceeded -j ACCEPT
$IPT -t filter -A INPUT -p icmp --icmp-type echo-request -j ACCEPT
#$IPT -t filter -A INPUT -p icmp --icmp-type ! echo-request -j LOG
$IPT -t filter -A INPUT -j LOG --log-prefix "[INPUT  DROP]: " 
--log-tcp-options --log-ip-options
$IPT -t filter -A INPUT -j DROP
