Mark Furneaux | Comprehensive Guide to pfSense 2.3 Part 5.4: NTP Server @TheUbuntuGuy | Uploaded February 2016 | Updated October 2024, 2 hours ago.
This video is an overview of the NTP service on pfSense (or any system for that matter) and how to add more servers. I will make a video in the future in which I will create a stratum 0 time server with a GPU module.
