Configure Cloudflare for Synology DDNS
Synology doesn’t support Cloudflare by default, but JoshuaAvalon has written a script to get this configured within DSM: from https://github.com/joshuaavalon/SynologyCloudflareDDNS/
SSH into your Synology NAS and complete the following steps:
- Download DDNS script — I recommend saving as cloudflare_domainname.sh if you have multiple domains.
$ sudo wget https://corcoran.medium.com/using-cloudflare-for-ddns-and-tls-certificates-on-synology-dsm6-1549e55d557fhttps://raw.githubusercontent.com/joshuaavalon/SynologyCloudflareDDNS/master/cloudflareddns.sh -O /sbin/cloudflaredns_domainname.sh2. Grant execute permissions
$ sudo chmod +x /sbin/cloudflaredns_domainname.sh3. Push configuration to DSM DDNS provider list
$ sudo echo "[Cloudflare Domain Name]">>/etc.defaults/ddns_provider.conf
$ sudo echo " modulepath=/sbin/cloudflaredns_domainname.sh">>/etc.defaults/ddns_provider.conf
$ sudo echo " queryurl=https://www.cloudflare.com/">>/etc.defaults/ddns_provider.conf
$ sudo echo " website=https://www.cloudflare.com/">>/etc.defaults/ddns_provider.confOpen Cloudflare dashboard for your domain name and complete the following steps:
- Get Zone ID for your domain
- Generate scoped API Token with the following permissions:
- Zone — Zone — Read
- Zone — DNS — Edit
Scope the token to your required domain name, if you have multiple Zones and/or require multiple DDNS entries for different hostnames
Return to DSM Gui and complete the following steps:
- Open Control Panel -> External Access -> DDNS
- Create “Cloudflare Domain Name”” DDNS entry in DSM Console:
- hostname: the a record of your domainname (mine syno.itsonpremises.dev)
- Username/Email: the ZoneID of your zone
- Password/Key: the scoped API token created in Cloudflare dashboard
Great stuff! DDNS should now be working, and you can move on to create the corresponding TLS certificates for your Synology NAS
