Ports Used by RU Server

Default communication port

By default, RU Server communicates with Viewer and Hosts via a single TCP port 5655. This port must be open/allowed on RU Server side as inbound port. See Making RU Server accessible.

On the Viewer and Host sides this port should be allowed as outbound port.

Module Port Direction
RU Server TCP 5655 Inbound
Viewer TCP 5655 Outbound
Host TCP 5655 Outbound

Custom communication ports

You can add multiple communication ports and assign them different roles in Port Manager. If you add your custom ports, make sure that you mirror the changes in the Internet-ID connection settings on the Viewer and Host sides.

Administration port

You can remotely connect to a running RU Server from another computer using Admin Console. By default, the TCP port 5670 is used:

Module Port Direction
RU Server PC TCP 5670 Inbound
Admin Console PC TCP 5670 Outbound

For more information, see the Remote connection section on the Admin Console page.
