@Patch yes, seeing the link for the earlier FR, I went to comment on that but couldn't as it was closed, hence the new FR with a link to the previous one. Not sure if that's the "right" way of doing it, but just wanted to bring it to their attention.
I'm hoping that if the new FreeBSD has it built-in, it requires minimal development on the pfSense side to include it as a feature - just a few Web UI tweaks?
