About Vista Remote Link (VRL) On-premises
Vista Remote Link (VRL) provides the ability to run Vista™ over the internet, using the standard Vista™ client outside the LAN and a reverse proxy server.
Use of a VPN or remote connectivity software is not needed. Your users can securely access the Vista™ database using any available internet connection. Wi-Fi connections found in most home networks and public hot spots can provide the needed internet connectivity.
The following diagram provides a high-level view of the system environment and shows how security is built into the design. You must set up your system in this manner to keep your data secure. For more information, see Vista Remote Link (VRL) System Requirements.
