When a CA UIM probe initiates a connection to a hub/robot/controler/probe it uses an dynamic port for outbound communication.
The dynamic port range is determined by the Operating System.

You can view the dynamic port range on a computer that is running Windows by using the following netsh commands:
- netsh int ipv4 show dynamicport tcp
- netsh int ipv4 show dynamicport udp
- netsh int ipv6 show dynamicport tcp
- netsh int ipv6 show dynamicport udp
