Well, let's see then. You won't need a build environment in the first
place. Just set up a virtual machine and add your changes. If you got it
all working, we will bother to get things into the source tree.

Go to /srv/web/ipfire/cgi-bin and copy a CGI script that is very similar
to what you want to do. For example the outgoing firewall script.

Then edit it until it does what you want it to do.

For example that. Create a basic configuration file and just build the
CGI that edits this configuration file.

When you are done, start with the script that actually adds firewall
rules.

The firewall is initialized in /etc/init.d/firewall.

CGI scripts go to html/cgi-bin/. All necessary configuration files have
to be created in lfs/cfgroot.
But again, first get this stuff working. We will see how to merge those
files when it is time for that.
