Chapter 13. rc.firewall file
This chapter will deal with an example firewall setup and how the script
file could look. We have used one of the basic setups and dug deeper
into how it works and what we do in it. This should be used to get a basic idea
on how to solve different problems and what you may need to think about before
actually putting your scripts to work. It could be used as is with some
changes to the variables, but is not suggested since it may not work perfectly
together with your network setup. As long as you have a very basic setup
however, it will very likely run quite smooth with just a few fixes to it.
 | note that there might be more efficient ways of making the rule-set,
however, the script has been written for readability so that everyone can
understand it without having to know too much BASH scripting before reading
this

OK, so you have everything set up and are ready to check out an example
configuration script. You should at least be if you have come this far. This
example rc.firewall.txt
(also included in the Example scripts code-base
appendix) is fairly large but not a lot of comments in it. Instead of looking
for comments, I suggest you read through the script file to get a basic hum
about how it looks, and then you return here to get the nitty gritty about the
whole script.
