Or if you want to access the mymbCONNECT24 server via mbDIALUP and receive the following red key symbol:

In both cases, you or your IT must have a public frontend SSL certificate issued by a third-party supplier, in order to ensure the trustworthiness and identity of the mymbCONNECT24 server.

The * .pem file must contain the private key and the certificate, that it looks like in the following screenshot:

The *.pem file must always begin with "-----BEGIN PRIVATE KEY-----" and end with "-----END CERTIFICATE-----". This means, that the header und footer must always be included. Please also pay attention to the number of characters (-).

Since * .pem files go in the UNIX direction, it is not possible to combine the private key and the certificate in a Windows text editor easily.

Further information and instructions, for example to create the frontend SSL certificate (* .pem file) with "OpenSSL" in Windows, can be found on the Internet.
