1. The Vigor 2820 only supports updating DynDNS on a regular basis, rather than when the IP address is detected as having changed. This breaks the first rule of their abuse policy: "Client updates at regular intervals: Clients should only send updates when a change is detected, but some are programmed to send updates at scheduled intervals, e.g. every five minutes or every hour."

2. Draytek routers are not officially supported by DnyDNS (see https://www.dyndns.com/support/clients/hardware/), probably as a result of point 1.

I have set the update interval to 1440 (= 24 hours) and will see how I get on.
