Oh, and I forgot to mention the most important reason why I always - and in
this case as well - like to configure things by editing a file, rather than
by running commands that change the configuration a bit:

Since /etc/sysconfig/iptables is a file, I can use my favorite file tools
on it: I can edit it using my favorite editor, I can save versions of it
using cp, cvs or whatever. When I edit the file, I see my changes in context
of the rest of the configuration (I don't need to keep one window with
"iptables -nvL" and enter iptable commands in the second). And yes - I
also heavily comment my iptables file to explain why I poked certain holes
in the firewall, or did other strange things.

If you do various "iptables -A" commands in the command line and later this
get saved automatically, in a month you might be scratching your head asking
yourself when or why or who ever added this rule. This can't happen to me -
because I put comments in the iptables file, and because it has an adjoined
RCS history which I can use to see who and when added this rule.

I'm not saying that automatic saving of firewall rules isn't good for
everyone, I was just explaining why I prefer not to do it, even when Fedora
(which I used) does appear to support this features.
