How to specify port and host for ng e2e using configuration

Question

How do you set the port and host for the command ng e2eusing the configuration file?

I know that the following statement can be used on the command line

ng e2e --port <port number> --host <host>

This works well, but it would be more convenient to set the port and address in the configuration file. I looked inside .angular-cli.jsonand found that there is a file with a name protractor.config.js, I could not figure out which settings to use in this file, there is a parameter there baseUrl, but changing this does not make a difference with the port used by the command ng e2e. It seems to be using a random port.

Besides baseUrl, I also tried to install portand seleniumPort, but they have no meaning.

After entering the command ng e2e, the following output will appear in the console

** NG Live Development Server is running on http://localhost:49155 **

As protractor.config.jsI have baseUrlset as http://localhost:50000. I watched the tests run, and I see that the browser uses an address http://localhost:49155that is not the desired address.

ng --version returns followin
