RouteMaster can handle many client connections simultaneously, using a wide range of protocols. The status bar at the bottom of the main UI gives a simple count of clients, but we can see additional information by enabling View Client Info from the Settings menu.
This displays a panel showing the enabled client protocols, and the number of incoming connections on each. You can expand each protocol individually, to see a list of client IP addresses and packet statistics for the protocol. A protocol caption in RED indicates a problem with that protocol server. Often this means that the selected listening port for the server is already in use, either by another process or due to two client protocols being assigned to the same port.
Here we see a single client connecting in using the WebPanel (AKA Websocket) protocol.
