Thank you for the clarification.
Please note that when connecting via Direct connection or Internet-ID connection via the self-hosted RU Server, you can choose any other port that is available for you. In case if you're using Direct connection, you can change the port to a custom value in the Host Settings -> Port tab and Viewer's Connection Properties window -> Network tab.
If you use Internet-ID connection via the RU Server, you can change the Server's communication port as well by following the instructions provided on this page.
Hope that helps.
