agreed, but only if I load the rules manually; i.e.
entering the rules via the command line such as
in D. Robbins doc:
http://gentoo-wiki.com/HOWTO_Iptables_and_stateful_firewalls#Should_I_take_this_tutorial

This will work if one loads the rules manually at the command line.
Where do I put a scirpt of iptables command, so it is read the
rule sets generated and then saved into /var/lib/iptables/rules-save?

Details on were to put the script and how best to 'loaded' into the boot
sequence via my script, is what is illusive.
[A] The best I can figure is
I put a script in /etc/, run it manually at the command line. The
ruleset will then be generated and saved into
/var/lib/iptables/rules-save. Upon reboot, the /etc/init.d/iptables
script reads the /var/lib/iptables/rules-save file.
After that if I want to modify the rules, I edit my script, run
my script manually, then issue:
"iptables-save > /var/lib/iptables/rules-save"
and my modifications are in the file that gentoo checks natively.
If I want to then test the rules, without rebooting, I issue:
/etc/init.d/iptables stop
/etc/init.d/iptables start
????

yes, understood.

understood.
What I'm looking for is the series of steps to
1. Where best to locate my script?
2. Insert (new) commands into the script.
3. convert new scrited commands into rulesets
4. Load rulesets into the /var/lib/iptables/rules-save
5. Restart the iptables/netfilter firewall
6. Test the (new) rulesset
7. Go to step 2 and repeat until a wonderful firewall results.
If what I work above [A] is correct then I just need some suggestions
as to where the scipt should be located under /etc/, for
consistentcy with gentoo mindsets.
If what I have written is incorrect, please correct with some detail?
PS: I'm not trying to be a pain, I just need to fully understand the
process on Gentoo.
