Worldwide access to your NAS server via a
dynamic DNS service (DynDNS)
Home users and private households normally access the Internet via an Internet service
provider. The Internet service provider issues an IP address (e.g.: 80.139.140.223) from its
address pool to your router upon connection. This IP address, however, is reissued with
every new connection to the Internet or at the latest after 24 hours. In order to maintain
permanent access to the router via the Internet, you therefore require a fi xed IP address.
So-called “DynDNS” providers assign a fi xed Internet address with name resolution to the
alternating IP addresses from your Internet service provider (e.g.: http://photocollection.
DDNSDienst.com).
Your NAS server is thus always accessible using the same Internet address
(http://photocollection.DDNSDienst.com) although your router receives changing IP
addresses from your Internet service provider.
This is achieved through the transmission of the router’s currently allocated IP address by a
DynDNS client (usually installed in the router or also in the NAS server) to the
corresponding DynDNS provider.
How to install and confi gure a DynDNS service in 3 steps:
1.
Set up a user account with a DynDNS provider (in the example,
www.DDNSDienst.com), most DynDNS providers offer free user accounts for this
purpose.
In the example described here, you set up an account with the DynDNS provider
www.DDNSDienst.com using the following data:
Host name: photocollection.DDNSDienst.com
User: photocollection
Password: ******
NOTE!
The address name, here “photocollection”, can be freely selected, assuming that
the name has not already been taken. The address extension “DDNSDienst.com”
is automatically assigned by the DNS service. The account is secured with a user
password.
2.
The name via which the NAS server can be accessed must be entered into the router
at home or, alternatively (if the router does not offer this option), it can also be set
up via the user interface on the NAS server. However, the most technically reliable
option is entering the name directly into the router.
The example here shows the set up process on a router:
If your router does not offer you the option of activating a DynDNS client, then the
DynDNS client can also be activated in the NAS server. This requires the DynDNS client to
be downloaded and installed in the package manager section of the administration
interface (as described in the manual in the chapter “
Package
”):
