Worldwide access to your NAS server via a dynamic DNS service (DynDNS)
13. Worldwide access to your NAS server
via a dynamic DNS service (DynDNS)
Home users and private households normally access the Internet via an Inter-
net 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 fixed IP address.
So-called "DynDNS" providers assign a fixed Internet address with name res-
olution 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 allocat-
ed IP address by a DynDNS client (usually installed in the router or also in the
NAS server) to the corresponding DynDNS provider.
13.1. 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.
