Qnap’a İnternet Üzerinde Erişebilmek İçin DDNS Ayarlarının Yapılandırılması

“Stay connected to your NAS from everywhere”

DDNS usage scenario

Dynamic Domain Name Service (DDNS) is a service used to map a domain name to the dynamic IP address of a network device.  QNAP NAS supports DDNS for quick access to the server on the Internet by an easy-to-remember domain name (URL) instead of a lengthy IP address.  Once the IP is changed, the NAS will automatically update the information to the DDNS provide to ensure it is always available for remote access.

1. Register DDNS service

1.1 Domain Name

A domain name is a translation operated by a DNS (Domain Name System) provider to convert an Internet IP address into a name (e.g. ‘74.125.153.104’ is www.google.com).

1.2 Register a free DDNS account

If your NAS is set up to use a dynamic IP address, you may register a free DDNS (dynamic DNS) account from a DNS service provider and assign a unique host name for easy access to your NAS on the Internet.

To register a DDNS account, please refer to the steps below:
Choose a DNS service provider. QNAP NAS currently supports the following DDNS service providers:

Create an account. Here we take http://www.dyndns.org/ as an example.

Visit http://www.dyndns.org/. Click ‘Sign In’ and ‘Create an Account’ to register a DynDNS account.

Create an account from Dyndns.com

Complete the form to create your free account.

Complete the form to create your free account

Click the link in the email for confirmation.

After you have created an account, a confirmation mail will be sent to your e-mail address

Click ‘Confirm Account’ and login DynDNS.

After account confirmation, login the DDNS service

Register a host name for your NAS.  A host name is a unique name that identifies your server.  Pick something you will remember.  For example, fill in ‘QNAP’ and select ‘dyndns-office.com’.  Then click ‘Add’.

The account summary is shown

Activate the host name.

The account summary is shown

Now you can login the NAS and set up the DDNS service.

1.3 Configure DDNS service on QNAP NAS

Login your NAS and go to ‘System Administration’ > ‘Network’ > ‘DDNS’.  Enter the DDNS information you registered from the DNS service provider.  You may also schedule the NAS to update the DDNS record periodically by configuring the ‘Check the External IP Address Automatically’ option.

After finishing the settings, the NAS will start to update the WAN IP to the DDNS provider for domain name mapping.  You can now connect to the NAS by the domain name (qnap.dyndns-office.com) on the Internet.

1.4 Lookup for your DNS if you need to verify:

To check that the domain name of the NAS is correctly mapped to its WAN IP, you may visithttp://www.mxtoolbox.com/DNSLookup.aspx.  Enter your domain name for DNS lookup and it will return your IP address.

2. Port Forwarding

If your NAS is located behind the NAT router, you need to open the port numbers on the router for remote access to the NAS. This function is available on most routers in the market and is often known as “Port Forwarding”, “NAT Server”, or “Virtual Server”. You may select the services with the corresponding port numbers to be opened on the router for Internet access. For example, to access the administration interface of Turbo NAS series, you need to open port 8080.
