The DynDNS client is set up in the administration interface of the NAS server under the
heading “
Network – DyDNS
”.
The following information is entered here:
- DynDNS
provider
-
The host name
- User
name
-
The password and re-entered password
And then the client is activated.
The client reads the Internet IP address from the router (80.139.140.223 in the example)
and sends it to the DynDNS provider. The DynDNS provider then allocates it to the rele-
vant account and the previously assigned Internet address (in the example:
photocollection.DDNSDienst.com). The router is thus accessible via the Internet by
entering the relevant Internet address (in the example: photocollection.DDNSDienst.com)
in a standard Internet browser.

The port forwarding function needs to be set up on the router.
Because the router does not offer the relevant DynDNS services for the NAS server, it needs
to be confi gured so that it can forward the requests from the Internet to the NAS server.
This function is called port forwarding (port mapping).
The settings for the port mapping function vary depending on the type of router and must
be taken from the operating instructions for the relevant router. The user interface on the
router is shown here as an example:
In order for the NAS server to be able to answer, the requests made to the primary fi xed
internal IP address (192.168.178.32 in the example) must be forwarded by the router to the
NAS server. This is set up using the following internet protocols:
-
http (NAS user interface): Port 80; tcp
- ftp:
Port
21;
tcp
Once the port forwarding function has been correctly set up on the router, the NAS server
can be accessed via the Internet under the name: http://photocollection.DDNSDienst.com.
NOTE!
All of the DynDNS providers and accounts described here are examples only!
Please note that some providers on the market offer free services while other
services are subject to a charge. Additional costs may also be incurred even when
using a free DynDNS account, depending on the relevant technical details and
enhancements.
