The ability to restrict on items such as domain names is very advantageous as it allows administrators to thwart attempts of internal machines attempting to connect out to known bad domains ( in other words, domains that may be known to have malware, illegal content, or other insidious pieces of data). This guide will walk through configuring a pf. Sense firewall device to use the pf. Blocker. NG package as well as some basic examples of domain block lists that can be added/configured into the pf.
