A VPN is typically deployed with each site having a unique private IP subnet (LAN). This simplifies traffic management and provides additional security in managing access on a site-by-site basis. However, sometimes it is necessary for a device or application to be installed at a remote location yet still be reachable within a local network (LAN). For example, an application that is using discovery protocol and is designed to work only in a LAN environment, or a controller or a meter that is reporting to a server with a local IP address. All these scenarios can be handled with our Edge routers, which is not the case with most other routers. In addition, we employ a LAN extension for disaster recovery solutions. In this scenario, when a local server is not accessible, a replicated copy at a different location can be made available and there is no need for any network changes. The server change will be fully transparent to local users and applications.
