Synology NAS (Network Attached Storage) does not have Dynu in its default dynamic DNS service provider list. But you can add Dynu to the list with very simple steps.

If your device supports it, you can add a custom DDNS provider by going to: Control Panel > External Access > Customize and entering the following:
