Are there any benefits to using an RD Gateway server instead of a VPN server? from networking
A RD Gateway allows you to establish a RDP connection to a Windows system, but tunneled through a HTTPS connection. It eliminates the need to allow RDP connections directly to a Windows system, which is considered a security risk.
To connect to a remote desktop session on a Windows system, you must configure your Remote Desktop Connection client to use a RD Gateway. You log onto the RD Gateway using your NetID. The RD Gateway can be accessed from any Internet connected client.
