About redefining the IP address and port number of the controller for connecting a CPE device

You can redefine the IP address and port number of the controller for connecting a CPE device when creating or editing an SD-WAN interface of the WAN type. This is necessary if the SD-WAN interfaces of the WAN type of the CPE device are connected to different networks, for example, to the internet and to a private MPLS network (see the figure below).

If your SD-WAN instance has multiple controller nodes, you need to redefine the IP addresses and port numbers of all controller nodes for connecting the CPE device. If the number of controller nodes does not match the number of specified IP addresses and ports, an error occurs and the values stay the same.

You need to restart the CPE device after redefining the IP address and port number to connect the CPE device to the controller.

In the diagram, the CPE device is connected to the controller through ports sdwan0, 1, and 2. The link goes through the Internet and MPLS.
