For a sufficiently new enough Red Hat box, system-config-firewall is
your friend. For older versions, I believe its
system-config-securitylevel. Both twiddle /etc/sysconfig/ip{,6}tables,
which you can also edit by hand (but that can be a wee bit error-prone
if you don't know what you're doing). Manually adding iptables
stuff on the cli can also be done, and then saved into those same
/etc/sysconfig/ip{,6}tables files by doing a 'service ip{,6}tables save'.

Now, for even OLDER RH, the "user-friendly" config tool would be
lokkit, but that's not been supported in ages, so far as I know...
