Access to NTP

Celona Edge nodes and Celona Access Point devices require access to NTP for initial time synchronization. Please ensure your firewall permits access from the Celona Edge and Access Points to NTP (typically this is server port 123).

Another, more preferred option for the initial time synchronization is DHCP option 42, which allows for NTP servers to be listed through DHCP. If your DHCP server is configured for DHCP option 42, then the Celona devices will utilize that DHCP option to configure their NTP time server.


Next up, let's activate your Celona subscription licenses within Celona Orchestrator so that you can start configuring your end to end private cellular network. To learn how, see this article on activating Celona subscription licenses.
