the configuration is the following:

ip name-server

ip name-server

ip ddns update method no-ip


  add http:// ****:****<h>&myip=<a>

interval maximum 0 0 5 0

interval minimum 0 0 5 0

interface Dialer0

mtu 1492

bandwidth 800

bandwidth receive 20000

ip ddns update hostname

ip ddns update no-ip host

ip address negotiated

ip flow ingress

ip nat outside

ip virtual-reassembly in

encapsulation ppp

dialer pool 1

dialer-group 1

ppp authentication chap pap callin

ppp chap hostname xxxxx@xxxxxxx

ppp chap password 7 xxxxxxxxxxxxxxxx

ddns don´t update

I have exactly the same problem....

When I type in the url manually on a webpage I get a 'GOOD' response from the No-IP ddns server - however, if I force ddns update by shut/no shut of the interface, I can see the ddns request going out and then the router times out stating error in updating ddns.
