To disable the netfilter firewall for Redhat (2.4 kernel distros)

run:
/etc/rc.d/init.d/iptables stop

That'll shut your firewall OFF

(At this point, check your system - see if things're now working for 
you. If so, then you've very likley found your problem and continue on. 
If not - just re-run the above command but change 'stop' to 'start' to 
restart your firewall using the stored config. Time to look elsewhere 
for your problem.)

Then, as root, run:
setup

Scroll down to the System Services tab - hit enter, then scroll down to 
iptables - uncheck it's box. This will prevent the stored netfilter 
configuration from being sent to the kernel by iptables at the next boot 
up, leaving all policies as 'ACCEPT' and no chains in any table.

You're done turning it off and keeping it off over a re-boot.

Now, if you want a firewall (and netfilter is *very* good!) - there are 
several good online guides as well as 'ready made' scripts to configure 
netfilter with iptables.

Find good rulesets (scripts) at:

At the LEAST, these are excellent starting points.

Find an excellent iptables/netfilter tutorial at:
http://iptables-tutorial.frozentux.net/iptables-tutorial.html

With these tools, most anyone should be able to setup a good, customized 
netfilter firewall.
