IP Domain configuration is used to translate your private mobile network resources to the existing L2/L3 network configuration on your infrastructure.

Configuring IP Domains with Celona Edge Clusters

As explained in detail in this article, IP Domains help translate cellular wireless to existing enterprise network resources for L2/L3 traffic forwarding.

Related network policies are managed via the Celona Orchestrator: select Edge Clusters from the side-nav menu in the Orchestrator to start. From the list of clusters displayed, select the name of the Edge Cluster for which you will be configuring the IP Domains.

Toward the end of the page, you will see two options to Add Internal IP Domain or Add External IP Domain. Note that multiple IP Domains of various types can be configured on each Celona Edge Cluster.

Internal IP Domains are fully managed by Celona Edge; the default IP Domain on every Celona Edge is Internal, NAT mode. Additional Internal, NAT mode domains can be added.

Configure an Internal IP Domain

  • Define the start and end IP address of the DHCP range that will be provided by Celona Edge.

  • Set custom DNS servers if required. Otherwise, devices will default to using Primary -, Secondary -

  • Click Add to save your new Internal IP Domain.

External IP Domains connect an existing VLAN or subnet to a specific Device Group in your private mobile network.

Configure an External IP Domain

  • Specify the IP address or subnet of the DHCP server in your existing network that will provide IPv4 addresses to devices in this IP Domain. Leave it blank to broadcast the DHCP request.

  • Enter the numerical VLAN ID that this IP Domain will belong to.

  • NOTE: Celona Edge switch interface should be a trunk port, with native VLAN untagged for management and tagged VLANs for client traffic forwarding

  • Once added, Celona Edge will create a corresponding VLAN sub-interface on its primary interface and request an IP address via DHCP broadcast on that VLAN. Leaving this blank connects the IP Domain directly to the default VLAN of the Celona Edge primary interface.

  • Click Add to save your new External IP Domain. It will be provisioned and ready for use on your Edge Cluster within seconds.
