900 ISR DDNS public ip unable to update automatically in dyndns

T0mTheCat
Level 1
Level 1

hi,

dyndns unable to capture my public ip address for my remote desktop connection via my dynamic dns instead of ip

Below are some attempt I did,

1) setting shorter internal time

2) use afraid.org and noip.com

3) reload/restart router

4) debug ip ddns update -> "Dynamic DNS debugging is on"

5) show logging -> no attempt in ddns connection

6) if I update my public ip manually in dyndns, i can establish the connection using avixxx.xxxxxx.xx

i can see the its update, i replied PM also. as per router concern it success, make sure you delete old entries on DDNS site and your correct validate ? by checking whatismyip address.

.134 i get results, is this correct IP ?

Hi Balaji,

.134 is not correct, it should be .33

If I Delete and re-adding it back, I worried the hostname may not be available.

Any other way I could do this?

Thank you.

I suggest to go to DDNS Site, remove all records and reinitiate, and check the time. as soon as it updates.(do you have many domains, remove and test only 1 )

 

 

i tested yesterday with my other router it still works as expected.
