As serendipity would have it, I keep running into posts online about how to restrict access to a WordPress site to users on a company LAN. I am not part of a LAN but have been in the past. Yes, there is the local server and A record/firewall-access method and a subdomain approach. There are drawbacks. I did some brief research and noted that none of the Visibility settings are a good choice. I then found Private Site plugin which is no longer supported for WP with Gutenberg and All In One Intranet I do not know if there are other similar plugins yet, that might make set up fast/easy.
However, I am posting here because I thought "Oh, this might be something that could be another USP for ClassicPress as a Business CMS. Ask the plugin author of the Private Site script to maintain it for ClassicPress or write a better one. When I was on the faculty years ago of a local university, we loved internal only websites – for courses, in particular, and ran into hiccups here and there, interestingly enough. This could be marketed to faculty, who have some freedom to choose, as well as business. "
There are 20K installs of the first plugin and 5K of the second one. The first works up to 5.0.7 WordPress.
I wondered what others thought before I delete this idea from my brain It appears I have a lot of ideas but not many that are sticky.
