Router has a interface with default gateway of a modem which has dynamic IP of x.x.x.x . Router has Private ip of 10.1.1.1 which uses PAT configured in modem to access internet .

Following is config

ip ddns update method mymethod
HTTP
add http://xxxx:xxxx@dynupdate.no-ip.com/nic/update?hostname=xxxx&myip=10.1.1.1
interval maximum 0 0 2 0
!

interface GigabitEthernet0/0.1
encapsulation dot1Q 1 native
ip ddns update hostname xxxx.no-ip.org
ip ddns update mymethod
ip address 10.1.1.1 255.255.255.0
ip virtual-reassembly in
crypto map INT_MAP
!


xxxxx#show ip ddns update
Dynamic DNS Update on GigabitEthernet0/0.1:
Update Method Name Update Destination
mymethod not available
Dynamic DNS Update on Dialer1:
Update Method Name Update Destination

it says mymethod is not avaliable and when i do a debug ip ddns update I dont see anything . Am i doing any mistake here.

If I understand you correcly, the device that you name a "modem" is propably in fact a router. If that device has the public IP on the outside and 10.1.1.x on the inside, then you have to configure DynDNS on that device.

Thnakyou for the reply. What if that router doesnt support config of dyndns. To simplify it yes, it should be done that way but I have been told that it was working fine before and it was a free account because of which it stopped working, I created account once more but dont see any debugs or updates.

Does anyone know of any known bug in c2900-universalk9-mz.SPA.152-3.T.bin IOS with regards to DDNS configuration. 

Looks like the service isnt starting, its even not sending any update of packet because there is nothing in the debugs and the DDNS service provider isnt receiving any packets . When all data is allowed and i can ping or reach that service from my router also.

I would expect that release to have plenty of bugs. Personally I never trust a .T release without any number.

15.2.4M9 (and 15.2.4M8 before) is my preferred release. 15.3.3M6 is a Cisco suggested release. Probably the best choice for your deployment.
