Enabling PF

[Michael Keen]

In 29.3.1. Enabling PF there is a reference to a default ruleset 
already created at /etc/pf.conf. In my install of FreeBSD 11 there is 
not a default ruleset there. The link to the pf tutorial at the top of 
Chapter 29 suggests that "on FreeBSD, you'll need to create a 
/etc/pf.conf file yourself." I'm just learning about FreeBSD and pf so 
maybe I have misconfigured something, or the documentation may need to 
be updated.

Thanks for all you do.
Mike
