["nicolas boussekeyt" <nicolas.boussekeyt@xxxxxxx>]

Hi, I want filter my firewall for raleka worm.

Actually, i have used :
iptables -A FORWARD -p tcp -i $EXTIF --dport 135 -j DROP
iptables -A FORWARD -p tcp -i $EXTIF --dport 135 -j LOG
iptables -A FORWARD -p udp -i $EXTIF --dport 135 -j DROP
iptables -A FORWARD -p udp -i $EXTIF --dport 135 -j LOG
iptables -A FORWARD -p tcp -i $EXTIF --dport 6667 -j DROP
iptables -A FORWARD -p tcp -i $EXTIF --dport 6667 -j LOG
iptables -A FORWARD -p udp -i $EXTIF --dport 6667 -j DROP
iptables -A FORWARD -p udp -i $EXTIF --dport 6667 -j LOG
iptables -A FORWARD -p tcp -i $EXTIF --dport 32767 -j DROP
iptables -A FORWARD -p tcp -i $EXTIF --dport 32767 -j LOG
iptables -A FORWARD -p udp -i $EXTIF --dport 32767 -j DROP
iptables -A FORWARD -p udp -i $EXTIF --dport 32767 -j LOG
iptables -A FORWARD -p tcp -i $EXTIF --dport 32768 -j DROP
iptables -A FORWARD -p tcp -i $EXTIF --dport 32768 -j LOG
iptables -A FORWARD -p udp -i $EXTIF --dport 32768 -j DROP
iptables -A FORWARD -p udp -i $EXTIF --dport 32768 -j LOG

But the worm is back.
