VNCmux can be used infront of other VNC servers to improve performance and stability of downstream applications. For this type of scenario the downstream application is configured to serve their VNC server via a non-standart port, for example 6000. Then external access to that port is disallowed. Finally vncmux is started to serve a VNC server on the standard port.
