DDNS not working have config

[whiteford]

Hi, I am trying to get DDNS to work on a Cisco 837 ADSL router, I've added below, but no luck:

ip ddns update method MyDDNS

HTTP

add http://***:***@members.dyndns.org/nic/update?system=dyndns@hostname=<h>&myip= <a>

interval maximum 0 1 0 0

interface Dialer1

description Outside FW

ip ddns update hostname ***.dyndns.com

ip ddns update MyDDNS

Log:

#sh ip ddns update

Dynamic DNS Update on Dialer1:

Update Method Name Update Destination

MyDDNS not available

capture the following debugs as well as the 'debug ip ddns update':

debug domain

debug dhcp

Check the NAT configuration as well.
