DynDNS

In this tab you can enable the use of address assignment by dynamic DNS (DynDNS) on the
mobile wireless interface. To do this you require one of the service providers that can be
selected below and the corresponding access data.
DynDNS is recommended when using OpenVPN and HTTPS.
Note
DynDNS only with a public IP address
DynDNS can be used only with a public IP address. Check this with your network provider.
If you log the CMR on to a DynDNS service, the device can be reached from the Internet
under a host name, for example "myName.dyndns.org".
Generally the CMR will not have a fixed IP address on the mobile wireless interface and will
not be registered under a host name. By using a dynamic domain name system (DynDNS) it
can however be reachable on the Internet. The public IP address is then made known by the
DynDNS service.
With each dial in to the data network and if the IP address is changed on the mobile wireless
interface, the DynDNS server is informed of the received IP address via HTTPS. An entry
with the IP address is written to the diagnostics buffer.
