DDNS - CISCO IOS ROUTERS

Hi All,

We have been asked by one of our customers to configure DDNS service on their 1841 with NOIP.com. This is not something we have done very often as most customers who run a DDNS service tend to use a client or server on the inside network. This customer wants the 1841 to take care of DDNS updates for their dynamic IP address changes. I have reviewed the Cisco documentation but does anyone have a simple config we could use to get this running??

As always all help greatly appreciated.

Regards,
