After implementing NTP Best Practices per adamONE instructions dated Dec 2 2021. Recently added a raspberry pi5 to my subnet and now it cannot sync time to NTP server (refer to attachment). Timeout waiting for reply from 1-3.debian.pool.ntp.org. Time shown on raspberrypi advancing from October 12 2024 but not synced with current date/time. Tried to restart time sync service same issue. Can set time to current time using ssh however time syncing not working due to no reply from NTP time servers.
You would want to exempt the pi from the DNAT rule.
Thanks Arthur I will try that and let you know.

Thanks Arthur that worked!

Would it not be better practice to change the configured NTP time server in the Pi to the gateway rather than make an exception in the firewall for the Pi?
Yes indeed it would be better.
I will try that in a few days.
