Very satisfied with one of these.

Also, don't get carried away with the number of servers or pools. A large number of servers may not improve your results.

When choosing pools, it's best to learn what type of servers they're bundling. For me, I have chosen 2.de.pool.ntp.org because it includes IPv6 servers and they tend to work best for me.

hi mb19,

Seems you are mixing up three possible situations:
1. LAN client requesting time from a NTP server on WAN
2. Opnsense router acting as an NTP client requesting time from an NTP server on WAN for synchronising its own clock
3. Opnsense router acting as a NTP server itself to serve time requests from LAN clients

situation 1: Appears to be working, since time of LAN client is synced.
situation 2: appears not to be working for unknown reasons. because of this, stiation 3 will also not work because of an unsynced clock on opnsense router.

From your example you say that for you can see traffic going out to WAN as well as coming back.
However, the NTPd daemon in Opnsense router does not appear to be synchronised.

Config looks ok.
