Setting up DynDNS with a Synology NAS
This guide explains how to access a Synology NAS via a domain name connected to the Internet with a dynamic IP address from Infomaniak.
⚠️ For additional assistance contact a partner or submit a request for proposal — also read the role of the host.
Prerequisites
- Have a Synology NAS connected to the Internet with a dynamic IP address.
- A dynamic DNS must have been created on the relevant domain with Infomaniak.
Link a Synology NAS to a Domain Name
1. Add Infomaniak as a Service Provider
- Open the management interface of the Synology NAS (DSM).
- Go to the Control Panel.
- Click on External Access (under the Connectivity section).
- Click on the Customize button (under the DDNS tab).
- Service Provider:
Infomaniak - Query URL:
https://infomaniak.com/nic/update?hostname=__HOSTNAME__&myip=__MYIP__ - Click on Save.
2. Add the Dynamic DNS to the Synology
Now that Infomaniak has been added as a service provider:
- Open the management interface of the Synology NAS (DSM).
- Go to the Control Panel.
- Click on External Access (under the Connectivity section).
- Click on the Add button.
- Service Provider:
Infomaniak(the profile created in the previous step). - Hostname:
The URLconfigured in the Manager during the addition of Dynamic DNS. - Username:
The usernameset in the Manager during the addition of Dynamic DNS. - Password:
The passwordset in the Manager during the addition of Dynamic DNS.
At this stage, the dynamic IP address of your Synology NAS will be automatically synchronized with your domain name.
3. NAT Configuration for Synology DDNS
In order to make your NAS accessible from the outside, it is necessary to configure the NAT of it. By default, Synology NAS uses ports 5000 and 5001.
You can reach your NAS using the following syntax: http://yourdomain:5000 or https://yourdomain:5001. Consult the official Synology documentation for more information.
4. Configure a Reverse Proxy
If you do not want to specify ports :5000 or :5001 in your URLs, it is possible to configure a Reverse Proxy from your Synology NAS, and thus redirect the URLs to port 443 for port 5001 and port 80 for port 5000 (official Synology documentation for this configuration).
