A couple of examples. $IPTABLES -A INPUT -p udp --sport 23 -s 0/0 -j LOG --log-prefix \ "Incorrect DNS source" $IPTABLES -A INPUT -i lo --sport 631 -j ACCEPT $IPTABLES -A FORWARD -o $EXTIF -p tcp --dport 137 -j DROP $IPTABLES -A FORWARD -o $EXTIF -p tcp --dport 138 -j DROP $IPTABLES -A FORWARD -o $EXTIF -p tcp --dport 139 -j DROP See http://www.linuxguruz.com/iptables/ for more and better information -- jludwig <wralphie@xxxxxxxxxxx>
