Anyone use OpenDNS with CenturyLink CBRAS Static IP?

CenturyLink has begun moving some of our WiFi circuits to CBRAS and I am having an issue getting OpenDNS to see the traffic.

The static Network ID is configured on the modem on ETH1 on our LAN Subnet correctly. The static IP is configured on our Ubiquiti UDM correctly and I have configured the OpenDNS IPs on the UDM. Internet traffic is passing and is being recognized as being on the static IP and not the dynamic IP assigned to the modem. The problem is, OpenDNS is not seeing any of this traffic and the status is "inactive" in the GUI.

If anyone is familiar with how CBRAS works, should I be applying the DNS IP's on our device or somewhere on the CenturyLink modem? I assumed it would be on our device since the modem is technically using DHCP to reach back to CenturyLink.

Thanks in advance.
