Since Synology (despite requests) still has not added DNS Made Easy as a listed provider (despite listing some really obscure services - go figure!) here is the steps to add a custom provider. DNS Made Easy Setup Create a new A-Record Set the name Set the IP (initial - any valid IP) Tick the "Dynamic DNS" tickbox Enter your chosen Dynamic DNS Password Save the new record When saving the record you will see a "Dynamic DNS ID" - note down this number. This will become the hostname on the Synology setup. Synology Setup Click "Customize" to add a new DDNS provider Name: DNSMADEEASY Query URL http://cp.dnsmadeeasy.com/servlet/updateip?username=__USERNAME__&password=__PASSWORD__&id=__HOSTNAME__&ip=__MYIP__ Click "Add" to add a new DDNS service Service Provider: *DNSMADEEASY Hostname: Dynamic DNS ID from DNS Made Easy Username/Email: your DNS Made Easy email Password/Key: your chosen DNSMadeEasy DDNS password Once you save the new DDNS provider you should see the status to go "Normal" in a green color. This means the update was successful. You should now be able to PING the DNS record or if you log in to DNS Made Easy the IP address should have changed to the external IP of your DiskStation.
