iptables, configured by system-config-securitylevel. Rules are saved in /etc/sysconfig/iptables

Here's a link for more info on iptables

how do you edit iptables.... gedit didnt work

[jcliburn]

Use your preferred editor and edit /etc/sysconfig/iptables.

To make the changes stick,

service iptables restart

Iptables writes its log outputs to the kernel log, typically /var/log/messages.

it's simple.
Use vi or vim, built-in FC.

[kurtdriver]

Neither vi, or vim is simple, I suggest emacs, or better yet download jed, which is easy to use and can be found here:http://rpm.pbone.net/index.php3?stat...earch=jed&dist[]=44&dist[]=41&dist[]=37&dist[]=31&dist[]=32&dist[]=1&dist[]=28&dist[]=2&dist[]=3&dist[]=4&dist[]=5&dist[]=7&dist[]=42&dist[]=36&dist[]=35&dist[]=11&dist[]=12&dist[]=34&dist[]=13&dist[]=14&dist[]=15&dist[]=17&dist[]=18&dist[]=33&dist[]=19&dist[]=20&dist[]=23&dist[]=24&dist[]=25&dist[]=26&dist[]=27&dist[]=29&dist[]=30&dist[]=38&dist[]=39&dist[]=40&dist[]=43&field[]=1&field[]=2
The world's longest URL? But aren't iptables edited from the command line, or one of the many graphical programs? From: /etc/sysconfig/iptables,
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
Anyway, the manual makes an interesting read, here's the first part:

NAME

iptables [-t table] -I chain [rulenum] rule-specification [options]
iptables [-t table] -R chain rulenum rule-specification [options]
iptables [-t table] -D chain rulenum [options]

DESCRIPTION
Iptables is used to set up, maintain, and inspect the tables of IP
packet filter rules in the Linux kernel. Several different tables may
be defined. Each table contains a number of built-in chains and may
also contain user-defined chains.

A quick and easy way of configuring iptables without spending days reading all the documentation is by using NARC http://www.knowplace.org/netfilter/narc.html. It will create the rules for you based on what you specify.
