A script to add Cloudflare as a DDNS provider on Synology NAS using the Cloudflare API v4.
SynologyCloudflareDDNS is a Bash script that allows Synology NAS users to configure Cloudflare as a Dynamic DNS provider. It solves the problem of accessing a Synology NAS with a dynamic IP address by automatically updating Cloudflare DNS records when the IP changes. The script integrates directly with Synology's DDNS settings using the Cloudflare API v4.
Synology NAS owners who use Cloudflare for DNS management and need reliable DDNS functionality for their self-hosted services.
Developers choose this script because it provides a free, self-hosted alternative to Synology's limited built-in DDNS providers, with the reliability and security of Cloudflare's infrastructure. It's specifically tailored for Synology's environment with straightforward setup.

Uses Cloudflare API tokens with limited permissions (Zone DNS Edit), reducing security risks compared to global API keys, as emphasized in the README under Token-Based Authentication.
Seamlessly adds Cloudflare as a provider in Synology's DDNS control panel, making configuration straightforward through the GUI after script installation, as shown in the setup steps.
Leverages Cloudflare's latest API v4 for reliable DNS updates, ensuring compatibility and security, which is highlighted in the project description and README.
Setup involves clear SSH commands to download and configure the script, with detailed instructions provided in the README for quick deployment on Synology NAS.
Requires enabling SSH and executing manual commands, which can be intimidating for non-technical users and introduces security risks if not properly managed, as noted in the access instructions.
The README lacks error handling details or logging information, leaving users to debug issues like API failures or network problems independently.
Tightly coupled with Synology's ecosystem and Cloudflare DNS; switching to another NAS brand or DNS provider would necessitate a complete replacement, limiting flexibility.
