By default iptables firewall stores its configuration at /etc/sysconfig/iptables file. You need to edit this file and add rules to open port number. This file only avilable under Red Hat Enterprise Linux 3 / 4 / 5 and above => Old Red hat Linux version => CentOS 4 and above => Fedora Linux We will use port 80 as example. Open port 80 Open flle /etc/sysconfig/iptables: # vi /etc/sysconfig/iptables Append rule as follows: -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT Save and close the file. Restart iptables: # /etc/init.d/iptables restart Restart iptables service Type the following command: # service iptables restart Verify that port is open Run following command: netstat -tulpn | less Make sure iptables is allowing port 80 connections: iptables -L -n Refer to iptables man page for more information about iptables usage and syntax: man iptables Referenced from : http://www.cyberciti.biz/faq/howto-rhel-linux-open-port-using-iptables/
