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

13.1. example rc.firewall

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.
