microfw is basically a very simple shell script which loads the needed
kernel firewall modules and loads custom iptables/ip6tables rules. You
can define your rules in the following files:

/etc/sysconfig/iptables
/etc/sysconfig/ip6tables

After that, just issue "microfw start" as root and you're set. To unload
all rules, issue "microfw stop".

That's it, folks :)
