The firewall section of the handbook states that the
rc.firewall file is an example.
You really should read the firewall section of the handbook
and use the working examples contained there.

This section of rc.firewall refers to valid values you can place in
rc.conf for firewall_type. In rc.conf you can name any of the types
defined in rc.firewall /or/ you can specify a file of your own
(instead of rc.firewall). I don't think you can invoke rc.firewall
/and/ another file you name.

Well, OK, surely there is a way to do that, but that functionality
is not the intent of this part of rc.firewall and rc.conf as I
understand it. I'm sure that if you put your custom rules in a shell
file that you can use rc or cron to load those rules at boot time;
you'd just need to be careful with rule numbering, maybe use ipfw
sets for rule ordering, etc.

Maybe easier to just

cp rc.firewall custom.ipfw, edit to your needs and use
