restart the gateway; the Embedded Web Server uses the provided certificate.
•
The certificate replacement process can be repeated when necessary (for
example, the new certificate expires).
•
It is possible to use the IP address of the gateway (for example, 10.3.3.1)
instead of a qualified DNS name in the Subject Name. This practice is not
recommended since the IP address is subject to changes and may not
uniquely identify the device.
•
The server certificate can also be loaded using ini file using the parameter
'HTTPSCertFileName'.

Client Certificates

By default, Web servers using SSL provide one-way authentication. The client is certain that
the information provided by the Web server is authentic. When an organizational PKI is used,
two-way authentication may be desired: both client and server should be authenticated using
X.509 certificates. This is achieved by installing a client certificate on the managing PC, and
loading the same certificate (in base64-encoded X.509 format) to the gateway Trusted Root
Certificate Store. The Trusted Root Certificate file should contain both the certificate of the
authorized user and the certificate of the CA.
Since X.509 certificates have an expiration date and time, the gateway must be configured to
use NTP (See Simple Network Time Protocol
Without a correct date and time, client certificates cannot work.
