About overriding the IP address and port for connecting an SD-WAN interface of the WAN type to the controller

You can connect SD-WAN interfaces of the WAN type to the controller even if they use different types of links, for example, the Internet vs a private MPLS network (see the figure below). You must manually override the IP addresses and ports for connecting to the controller when creating or editing an SD-WAN interface of the WAN type.

Connecting the CPE device to the controller via two different communication channels

If your SD-WAN instance uses multiple controller nodes, you must override IP addresses for all nodes. If the number of controller nodes does not match the number of specified IP addresses, an error occurs and the values stay the same.

You must restart the CPE device after overriding the IP address and port for connecting an SD-WAN interface of the WAN type to the controller
