iptables... an easy way

I have been trying to open a trivial MySQL port in the fedora server box - just wanted to use desktop MySQL Client (like freeware EMS SQL Manager Lite for MySQL) rather than ubiquitous phpMyAdmin. I never understood this perplexing iptables command and its rules.

The easy way is to do a "Copy and paste" of a line from /etc/sysconfig/iptables and changing the port number (3306 for mysql - default).

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT

Restarting the iptables service does the remaining job.

service iptables stop
service iptables start
