pf/opnsense essentially provide web interfaces to the underlying
FreeBSD OS tooling. In this case I'm running plain OpenBSD. That means
configuring the system is mainly done by reading and writing text
files and doing stuff at the command line. There's a whole bunch of
reasons why some people prefer one way or the other or even mix things
up a bit. My recommendation is, if you're interested, have a go
administering a system without a web interface and see how you feel! @Edgarallenpwn@selfhosted
