 This article provides an overview of the Azure Arc gateway for Azure Local. The Arc gateway can be enabled on new deployments of Azure Local running software version 2408 and later. This article also describes how to create and delete the Arc gateway resource in Azure.

This component runs as a service (Called  the **Azure Arc Proxy**) and works as a forward proxy for the Azure Arc agents and extensions. The gateway router doesn't need any configuration from your side. This router is part of the Arc core agentry and runs within the context of an Arc-enabled resource.
