I have two questions.
1. TCP and UDP ports are using the same systems? For example, TCP port 12000 uses the Listener to do after, UDP port 12000 if you can use it?
2. When the port is not specified when,. Net default ports 1025-5000, then, when there is no available ports in the region when,. Net return an error, or use it in other regions of the ports? Thank you to answer.
