Celona Access Points, Edge, and Orchestrator must communicate over the existing enterprise LAN/WAN infrastructure to enable zero-touch provisioning and cloud-based management of the Private Wireless network. For seamless Day 0 & Day N operations of the Celona Private Wireless network, enterprise firewalls must be configured to allow specific discovery, management, provisioning, and troubleshooting functions.

Please refer to the following tables for detailed firewall configurations to allow communication between Celona AP, Edge, and Orchestrator (software version 2206 & above).

Access to NTP

Celona Edge nodes and Celona Access Points 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 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.

Support for Native Apple Apps (Facetime, iMessage)
