Dear all, When i look at "IPTRAF", i see lot of broadcast traffic that using port 137 and 138, how to make rules that can block all traffic in port 137 and 138, i already try to use this rules but its no works... iptables -A INPUT -p tcp --dport 137 DROP iptables -A OUTPUT -p tcp --dport 137 DROP iptables -A INPUT -p udp --dport 137 DROP iptables -A OUTPUT -p udp --dport 137 DROP iptables -A INPUT -p tcp --dport 138 DROP iptables -A OUTPUT -p tcp --dport 138 DROP iptables -A INPUT -p udp --dport 138 DROP iptables -A OUTPUT -p udp --dport 138 DROP iptables -A INPUT -p icmp DROP Thank's David Kandou
