**UPDATE:** After further research, configuring _chronyd_ on the IDM Server and some clients to sync with pfSense NTP Server, it appears good, pfSense NTP UI is all I need to make any adjustments and I don’t need any SRV record look-ups, because the IDM will default to using _chronyd_ configuration. ```auto [root@idmserver1c etc]# systemctl status chronyd ● chronyd.service - NTP client/server Loaded: loaded (/usr/lib/systemd/system/chronyd.service; enabled; vendor preset: enabled) Active: active (running) since Mon 2023-04-03 12:39:42 MDT; 2 days ago Docs: man:chronyd(8) man:chrony.conf(5) Process: 7166 ExecStart=/usr/sbin/chronyd $OPTIONS (code=exited, status=0/SUCCESS) Main PID: 7168 (chronyd) Tasks: 1 (limit: 48621) Memory: 1.3M CPU: 569ms CGroup: /system.slice/chronyd.service └─7168 /usr/sbin/chronyd -F 2 Apr 03 12:39:42 idmserver1c.kbbn-7.com systemd[1]: Starting NTP client/server...

So whilst your configuration shows this, the `chronyc sources` will show the members of the pool. This is normal, and it’s not a problem. Otherwise, I’m having difficulty actually understanding what your problem is? As far as I see, it’s working how it should. ---

> [@iwalker](#): > > Otherwise, I’m having difficulty actually understanding what your problem is? As far as I see, it’s working how it should. Okay sounds good, I’m knew at this part of my learning curve and just needed a clarification. I removed that setting inside chrony.conf, and set the server directive to point to pfSense LAN Gateway for its NTP Server and added the pools there. This way I will just have a single configuration to deal with. ---
