The idea is to keep consistency of adding DDNS in the Synology Control Panel External Access, so user can manage all DDNS records in one place. Advantages:

• Synology DSM update all DDNS items every day
• Synology DSM has internal checking for WAN IP change, and trigger the DDNS update in minutes
• Scripts will check the DNS record first, do not update if current IP is the same
• IPv6 is supported
• Scripts log event results to an easy accessible file

How to use dsmCloudflareDdnsModule.sh

Access Synology via SSH

1. Login to your DSM
2. Go to Control Panel > Terminal & SNMP > Enable SSH service
3. Use your client to access Synology via SSH.
4. Use your Synology admin account to connect.

Run commands in Synology

1. Download dsmCloudflareDdnsModule.sh from this repository to /sbin/cloudflareddns.sh or any folder as you like

wget https://raw.githubusercontent.com/myrenyang/SynologyDsmDdns/main/dsmCloudflareDdnsModule.sh -O /sbin/cloudflareddns.sh

2. (Optional) Update the script to change the log file location, by default it is /var/services/web/logs/ddnsLog.txt, that means you can see the log on website if you have enabled Web Station.

3. Make it executable in /sbin/cloudflareddns.sh

chmod +x /sbin/cloudflareddns.sh

If you put the it in another folder, just make a link

ln -s /whatever-path-of-the-folder/cloudflareddns.sh /sbin/cloudflareddns.sh

4. Add cloudflareddns.sh to Synology Config Panel

Append following config to /etc.defaults/ddns_provider.conf.

[Cloudflare]
        modulepath=/sbin/cloudflareddns.sh
        queryurl=https://www.cloudflare.com
        website=https://dash.cloudflare.com

You can use VI editor or following commands

echo "[Cloudflare]" >> /etc.defaults/ddns_provider.conf
echo "        modulepath=/sbin/cloudflareddns.sh" >> /etc.defaults/ddns_provider.conf
echo "        queryurl=https://www.cloudflare.com" >> /etc.defaults/ddns_provider.conf
echo "        website=https://dash.cloudflare.com" >> /etc.defaults/ddns_provider.conf
echo "" >> /etc.defaults/ddns_provider.conf

Note, queryurl does not matter because we are going to use our script but it is needed.
