Starting Listening VNC Viewer Plus

You can start VNC Viewer Plus in such a way that it does not connect to AMT Server but rather waits for AMT Server to connect to it. This is called a reverse connection.

command, for example vncviewerplus.exe -listen 4567.

Note that a Fast Call for Help session is likely to be routed via proxy servers. If these require authentication, you must specify the necessary credentials before a session starts. To do this, select Default Options to open the Options dialog, and follow the instructions in Connecting via proxy servers to specify a user name and password for both an HTTP and a SOCKS 5 proxy server.

Note: There is no need to specify network addresses and ports for proxy servers. This information is provided by the MPS.
