Cradlepoint CBA850: First Time Setup with Firewall/Router

So, you just got your hands on an INS provisioned Cradlepoint CBA850 and you’re ready to connect it to your Firewall/Router. The steps below will show you how to obtain the IPv4 Address, Subnet Mask, Default Gateway and DNS from the CBA850 and how to properly connect the CBA850 to your Firewall/Router.

NOTE: Cradlepoint CBA850's LAN 2 port is the designated IP Passthrough port.

1) Power up the CBA850 and wait for it to connect to the cellular network.

2) Disable the Wi-Fi of your Windows PC. Using an Ethernet cable, connect the PC to LAN 2 port of the CBA850 (screenshot below)

NOTE: Ensure the PC is configured for DHCP connection method.


3) Perform an IP config check (ipconfig /all). Note down the IPv4 Address, Subnet Mask, Default Gateway and DNS values.

4) Disconnect the PC from LAN 2 port of the CBA850. Reboot (power-cycle) the CBA850 and wait for it to connect to the cellular network.

5) Program the Firewall/Router's WAN interface with the parameters taken in step 3 above.

6) With the CBA850 powered up and connected to the cellular network, connect the Firewall/Router’s WAN port to LAN 2 port of the CBA850.

After performing the steps above, the Firewall/Router should now have the cellular IP of the CBA850.
