چگونگی نصب kiss firewall
Brief Summary
KISS My Firewall is a FREE iptables script designed for a typical web server. It takes advantage of the latest firewall technologies including stateful packet inspection and connection tracking. It also contains some preventative measures for port scanning, DoS attacks, and IP spoofing, among other things.
KISS My Firewall 2 is very easy to install and does not require any initial configuration. It will work with any stock installation of Ensim WEBppliance Basic & Pro, Plesk, and Webmin. Cpanel installations require some modifications. Available at: KISS My Firewall - iptables for a typical web server
What's New in Version 2?
The biggest change is that it does not require any initial configuration. With version 2, you won't automatically lock yourself out of your server unless you set some of the variables incorrectly. It also does extensive error checking and is distributed as a tar file. This solves a lot of the issues that were present with the older version. In addition, version 2 is highly configurable and was tested to work with the latest version of iptables - version 1.2.8.

#$IPTABLES -A INPUT -i eth0 -p udp --sport 53 --dport 53 -m state --state NEW -j ACCEPT
#$IPTABLES -A INPUT -i eth0 -p tcp --sport 53 --dport 53 -m state --state NEW -j ACCEPT
#$IPTABLES -A OUTPUT -o eth0 -p udp --sport 53 --dport 53 -m state --state NEW -j ACCEPT
#$IPTABLES -A OUTPUT -o eth0 -p tcp --sport 53 --dport 53 -m state --state NEW -j ACCEPT

$IPTABLES -A INPUT -i eth0 -p udp --sport 53 --dport 53 -m state --state NEW -j ACCEPT
$IPTABLES -A INPUT -i eth0 -p tcp --sport 53 --dport 53 -m state --state NEW -j ACCEPT
$IPTABLES -A OUTPUT -o eth0 -p udp --sport 53 --dport 53 -m state --state NEW -j ACCEPT
$IPTABLES -A OUTPUT -o eth0 -p tcp --sport 53 --dport 53 -m state --state NEW -j ACCEPT
6) Cpanel Users Config - other users ignore this step
In the /usr/bin/kiss file scroll down until you see the line: TCP_IN and replace it with this.
TCP_IN="20 21 25 53 80 110 143 443 995 2082:2083 2086:2087 2095:2096 3306"
Now find the line that says TCP_OUT and replace it with this.
TCP_OUT="21 22 25 37 43 53 80 443 873 2089"
