RUT 240 - DynDns Public IP not updating


Could you please clarify what firmware version is installed on your device?

In the DDNS configurations, there are two fields - check interval, and force interval. The check interval specifies how often the IP address should be checked, while the force interval, how often the IP address updates should be sent to the server. You can hover over those options to see a tooltip:


Would it be possible for you to share some screenshots of your DDNS configurations, as well as the status which is visible on the Services → Dynamic DNS page? Make sure to hide sensitive information, such as IP addresses, etc.

Also, to avoid further confusion for the other users, could you please clarify where you have found the information that DDNS only works with static IP addresses? Thank you!

Kind Regards,
