Hi There
THe RUT240 DYNDN config is shown below. dyndns.org is probably the biggest dyndns provider and we manage over 1000 domains through this service on several hardware models, so using another dyndns provider is not practical But I cant see how the provider would be an issue in this case. It seems that when a failover, network re-registration event , or a reboot, the dyndns update script should be triggered. What is strange in the case below, even if not immediately is that after 10 minutes at least (the ip check interval) it should detect that the WAN ip has changed and then update. But it never does in wired wan....
this leads me to wonder if there some RUT240 Firewall configuration that is preventing the dns process from calling the dyndns URL via the wired WAN port as apposed to the Mobile WAN. dns updates via Mobile WAN are fine.

Dynamic DNS allows you to reach your router using a fixed hostname while having a dynamically changing IP address.
