Thank you for your message.
First, let me elaborate on three possible connection types:
1. Direct connection
by an IP address or DNS name. In this case no intermediary server is used. Viewer connects directly to Host.
2. Internet-ID connection
: hosted by us[/B]. This is the simplest setup - just follow this tutorial
to get everything up and running in seconds. You don't have to change any ports.
3. Internet-ID connection hosted by you (RU Server).[/B] You point both
Host (Settings -> Internet ID connection settings) and Viewer (selected connection -> Properties -> General tab -> "Change" button) at your RU Server. Note that for Host this setting is global whereas for Viewer it's on a per-remote-connection basis, that is you can have records in your address book that use different types of connection. Once you specified your RU Server instead of the default ID server at both ends, use the ID of the remote computer in order to connect just like you would do if you used the second type above.
I would recommend you exactly follow the RU Server documentation
as it explains everything you need to know for this advanced (yet powerful) option.
Don't hesitate to write here if you didn't have any success with configuration.
