dynamic DNS publishing an old WAN IP was created by mbames
My 2925 must have dropped its connect on Saturday (via a 130) and reconnected with a new WAN IP from Sky.

However the Dynamic DNS part of the router didn't realise and kept publishing the wrong IP (old) address. The GUI screens (from the dashboard) showed the new IP address, but the Dynamic DNS logs suggested the router was pushing the old IP address out to no-ip.org

Tried a force, no go lucky. DIsabled and re-enabled DynDNS, still no go. Rebooted, and then the router published the correct IP address. This mean I lost remove connectivity to the router (no VPN, etc).

I've got a screen shot of the various screens (dash vs Dyn DNS log).

Has anyone else experienced this? I've never seen this before in years of use (2800, 2820s, 2925).

Thanks,
Matt
