Abstract
A process can include determining a plurality of Network Address Translation (NAT) routes associated with respective edge routers included in a same virtual private network (VPN) for communicating with a software-defined wide area network (SDWAN). A process can include identifying a first subset of the plurality of NAT routes as mapped to a first public NAT address included in a NAT pool associated with the VPN. A process can include tagging each NAT route of the first subset with a tag value indicative of a preferred router for receiving return traffic of the respective NAT route. A process can include routing traffic on a respective NAT route of the plurality of NAT routes based on applying, at an SDWAN controller, a corresponding control policy matching the tag value of the respective NAT route.
