I would love to go pfsense but I wanted to do this on a bare FreeBSD install for learning experience. Especially learning pf as I come from the iptables way of doing things and find pf much more readable, and sane lol. Also it would help me learn a bit about zfs, snapshots, and boot environments as well. That’s the main reason why I go the route of masochism, to learn as quickly and effectively as possible. > > > Thank you, > Lewis To learn how to install and operate a FreeBSD system, "Absolute FreeBSD" 3 e. by Lucas is very practical: https://mwl.io/nonfiction/os#af3e Lucas also has several smaller books that go deeper into specific subjects: https://mwl.io/nonfiction/os#fmzfs https://mwl.io/nonfiction/os#fmaz https://mwl.io/nonfiction/networking#n4sa The WikiPedia page "PF (firewall)" has a list of References and a list of Books.
