I have cisco 1801 with ADSL with Dynamic IP Address. I want to configure it for Dynamic DNS to remotely management. I have created my account in and configure the Router with the following configuration.

interface Dialer1
description ADSL
ip ddns update hostname
ip ddns update no-ip
ip address negotiated
ip nat outside

ip domain name
ip name-server
ip name-server
ip auth-proxy max-nodata-conns 3
ip admission max-nodata-conns 3
ip ddns update method no-ip

interval maximum 0 0 5 0

ip http server
ip http secure-server
ip dns server

But I am not able to telnet or HTTP on the following host

even NSLOOKUP is not working for this.

Please let me know what I am missing.

I'm not sure if there are specific DDNS debug commands, but if you take "debug ip http client" with "term mon", you should see how the DDNS registration goes.
