How to use vnc remote desktop? VNC workflow (use steps):

(1) Start the vnc server on the server side.

(2) VNC client connects to VNC server through browser or vnc viewer.

(3) The VNC Server sends a dialog window to the client, asking for the connection password and the VNC Server display device accessed.

(4) After the client enters the online password, VNC Server verifies whether the client has access permissions.

(5) If the client passes the verification of VNC Server, the client requires VNC Server to display the desktop environment.

(6) The VNC Server requires the X Server to hand over the screen display control to the VNC Server through the X Protocol.

(7) VNC Server will be sent to the client by X Server's desktop environment using VNC communication protocol, and the client is allowed to control the VNC Server's desktop environment and input device.

How can a VNC client on an external network remotely desktop an intranet host?

1. Install and log in to nat123 client to add an intranet mapping record on the local VNC server host installed in the target intranet, or on another interworking server in the local LAN. Map the intranet IP (and VNC port) to an automatically generated domain name address (or fill in your own registered domain name) and an automatically generated internet port.

2. After nat123 maps the domain name, VNC on the Internet can connect and access through the domain name (plus the Internet port).

3. When selecting the mapping type, it is recommended to select full port mapping or non website mapping. The difference between the two methods: after full port mapping (no need to fill in the intranet port), P2P visitors using nat123 (the same as those installed on the client) need to be installed on the access side at the same time, and the intranet and internet ports are consistent. After the mapping type of non website applications (the intranet port needs to be filled in), the internet port is automatically generated, and the internet port is used for direct access connection in the internet.
