Overview
This document describes how to enable Tencent Cloud's dynamic DNS (DDNS) in Synology NAS, so as to access Synology NAS with a public IP over the public network by using a domain.
Note:
In the process, fees may be incurred by domain purchase, but enabling DDNS and applying for a certificate are free of charge.
Prerequisites
You have a Synology NAS account with admin permissions.
The Synology NAS has a public IP.
You have an available domain hosted with DNSPod. Directions
Note:
Your API key represents your account identity and granted permissions, with which all Tencent Cloud resources under your account can be manipulated.
For the security of your assets and services, store your keys safely and change them regularly. Do not upload or share them via any method (such as GitHub).
1. Log in to your Synology NAS with an admin account and click Control Panel > External Access > DDNS > Add.
2. In the Add DDNS pop-up window, enter the information.
Service Provider: Select Tencent Cloud.
Hostname: Enter your domain.
Username/Email: Enter the obtained SecretId.
Password/Key: Enter the obtained SecretKey.
Get a certificate from Tencent Cloud and set it as default: After this option is selected, the system will automatically apply for a free TrustAsia SSL certificate for you and replace the default NAS SSL certificate with it.
Note:
Click
Test Connection
to test the connection. If the
Status
is
Normal
, the connection is established successfully.
3. Click OK. Wait for the DNS record to take effect. Then, you can use the domain to access your Synology NAS.
Note:
The DNS record usually takes 10 minutes to take effect.
Step 3. Manually update the DDNS (optional)
1. After configuring the settings, click Update Now, and the system will update the DDNS record. Then, check whether the Status is Normal.
2. Go back to the My Domains page and click your domain to check whether the record value has changed to your public IP. If so, the settings are successfully applied.
If not, troubleshoot according to the following FAQs.
FAQs
What should I do if the domain cannot be accessed after the settings are configured?
Check whether your IP is a public IP. Specifically, access the IP obtained by the Synology NAS via the browser in the public network environment. If the access succeeds, the IP is a public IP.
After configuring the settings, you need to wait for the DNS record to take effect (which usually takes 10 minutes) before access. Then, run the ping domain command to check whether the returned IP is your public IP.
What should I do if the record value does not change after the manual update?
Check whether the SecretId and SecretKey are entered correctly.
