Dear All,

For the Firewall setting, how can we use the ftp and ssh service ?

For file 1 :

#!/bin/bash

modprobe ip_tables
modprobe ip_nat_ftp
modprobe ip_conntrack
modprobe ip_conntrack_ftp

iptables -F
iptables -X
iptables -F -t nat
iptables -X -t nat
iptables -F -t mangle
iptables -X -t mangle

iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -t nat -P OUTPUT ACCEPT
iptables -t nat -P PREROUTING ACCEPT
iptables -t nat -P POSTROUTING ACCEPT
iptables -t mangle -P PREROUTING ACCEPT
iptables -t mangle -P POSTROUTING ACCEPT
iptables -t mangle -P INPUT ACCEPT
iptables -t mangle -P OUTPUT ACCEPT
iptables -t mangle -P FORWARD ACCEPT

For file2

iptables -P INPUT DROP
iptables -A INPUT -i lo -j ACCEPT
iptables -A INPUT -m state --state ESTABLISHED -j ACCEPT
iptables -A INPUT -p tcp --dport 21 -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -j ACCEPT

Edward.
