Introduction

...

Via the custo dynDNS DynDNS service it is possible to make rdt RDT transfer in diag custo diagnostic 5.x without a fixed external IP address.
Authentication The authentication is based on the custo cloud server login (kybe login).

Configuration

Start

If nothing is set up yet, the "dynamic URL and SSL" appears as follows:

...

cloud server

As a custo med retailer sales partner please go the retailer web page of the custo cloud server:

Please go to http://kybe.customed.de/CustoCentral/retailer/ and , log in with your sales partner account and create a customer account (if the customer does not yet have any). Then wait some minutes until the  the user credential information is distributed among the different cloud servers.

...

Then open a either the Internet Explorer or the MS Edge browser on the server where the custo diagnostics diagnostic server is installed and open the following web pages:

httphttps://kybe.customed.de/CustoCentral/ (Error 404 will appear, but's ok)

and

https://letsencrypt.org/

...

Now it is time to open up the firewalls (the internet firewall or router, the Windows Firewall and the virus scanner) for the external communication.

An example how to open up an inbound port from the internet to the router Fritz Box can be found here:

https://avm.de/service/fritzbox/fritzbox-7590/wissensdatenbank/publication/show/893_Statische-Portfreigaben-einrichten/ (section 3 to allow access to the Fritz Box itself is not relevant). The port which needs to be forwarded from the internet to the custo diagnostics server is the SSL port, which per default is TCP port 8443. However the installation may use also 18443 or 28443.

To test the connection from outside you can try to open the connection in a browser like this: https://<your-external-ip>:<configured-port>/diag
If the "WebViewer-coming-soon picture is coming up the external connection will be run.

Then go back to the Service Center to the Dynamic URL and SSL section:

...

By default the DynDNS configuration URL is set to https://null:8080. There is no need to change that URL: . This will be done automatically if you click on "Install Dyn URL Setup DynURL and certificate".

The configuration works automatically and is done by pressing click on Setup DynURL and certificate. Creating the certificate takes a few minutes.

If everything worked, the dynDNS DynDNS name appears in the field DynUrl (1) and the period of validity of the certificate at DynURL Status (2)

Get secured CustoCfg.ini

Saves the custoCfgCustoCfg.ini with the new URL to the disk so that it can be used for future purposes.
