State of knowledge

October 2020

This article explains which ports must be released for the respective estos product components.

Under "Direction" there is

  • "in" for incoming connections on the computer of the program itself
  • "out" for the port that is addressed on the computer of the target program
  • Example: The UCClient connects "out" to the UCServer on 7222. This is the port that must be accessible on the server.

Usually, the port number for "out" is searched for and set by the TCP stack itself and cannot be specified/changed on the computer of the program itself.
