Network Connections
Click the Network Connections button to display the status of all current (active) network connections
to or from your RouteFinder. It also shows you all of the established TCP sessions and all of the TCP
and UDP ports that the RouteFinder is listening to for incoming connections. (Connections through the
RouteFinder are not shown).
TCP and UDP Connections Example

you requested the output.
