pfsense is an appliance and a commercial product based on FreeBSD, but not FreeBSD, so yes - as with other derivatives, discussion of it is banned on the official FreeBSD forums. In fact all technical discussion of other OS is banned.

That, however, is not at all relevant to this thread. (It may be relevant to your failed trolling attempts at the FreeBSD forums, but that's of no interest to anyone here.)

I can speak from personal experience about pfsense. Years ago I ran it on an IBM 300 PL 667 MHz unit with 512 MB RAM. It was an exceptional firewall. The last time I used it the software was free.

I've already provided one, but I agree on schooling themselves if they're going to use pf.

I have the pf ruleset I use on my laptops and the same ruleset modified for people who use CUPS included in the Beginners Tutorial on my site:

Building A FreeBSD Desktop From Scratch

It has a target audience of a Windows user who has never used the commandline and walks them step-by-step through installation of the FreeBSD Base System, compiling 3rd party programs from ports, to landing on a fully functional Fluxbox desktop with instructions and examples of required editing of System and Security files before surfing the web.

I have another tutorial on How To Spoof Your Ethernet MAC Address Using FreeBSD and how to reassign your original MAC without shutting the interface down. Some Free as in FreeBSD wallpapers I made and more original material in the works.

That to include a Lesson in using ports that explains the oft asked question of why use ports in a Beginners Tutorial.

I've upgraded the site with a whole new look to reflect trihexagonal.org after being offline for over a year with the last update 5-3-21. All in handwritten valid XHTML 1.0 Transitional and Level 3 CSS with no scripting or ads for your benefit in learning to use FreeBSD as a desktop OS like I do.
