Firewall Startup Configuration files

[Magnus Sundberg <Magnus.Sundberg@dican.se>]

Dear sirs,
I am in the process of migrating my old redhat 7.1 based firewall 
to Debian.
On the old firewall, I replaced the /etc/init.d/iptables script 
with a huge home written script.
This script loaded all filter chains, one by one, and did some 
changes to /proc/sys/net/ipv4/
	ip_conntrack_max
	ip_local_port_range
	tcp_en
	...

Now,
I want to have one start script that sets up the kernel 
parameters, and I want to have my separate config script, with 
all chains, then I want to run init like:

<Setup kernel parameters>
iptables start

to configure my firewall, I would do something like

# run_my_firewall_chain_script
# /etc/init.d/iptables save

Well thats the background information, sorry to keep it so long.

Which configuration file is supposed to keep the kernel parameters?

Sorry for such a long simple question.

Is there a FAQ for this list?

regards,
Magnus Sundberg
